December 2, 2019 Version update Eric Changed $APLSUB/GETRLS.FOR. $INSUNIX/INSTEP1, $SYSPERL/install.pl, $SYSPERL/update.pl, $SYSPERL/ZXHLP2.PL, $SYSPERL/LaCook.PL, $UPDUNIX/UPDCONTROL, $SYSUNIX/AIPSPATH.CSH, $SYSUNIX/AIPSPATH.SH to make 31DEC20 instead of 31DEC19 - also fix dates in install.pl. Moved nowhere. 15431. December 4, 2019 Compiling Eric Added -c to the compilation done by $SYSUNIX scripts FC and AIPSCC. Took the -c out of FDEFAULT.SH AND CCOPTS.SH versions $SYSUNIX, $SYSLINUX, $SYSLNX64, and $SYSMACIN. Other versions (should they ever be used again) will simply have an excess -c. All of this is in an attempt to make the compilation of XAS work during installation. Moved to 31DEC19 16 December. 15432. December 9, 2019 ELINT, PLOTC Eric Added adverbs DO3COL to color the calibration sources, DOALL to plot all times after using TIMERANG to limit the data used in the fit, and PIXRANGE to select a fixed plot range if desired. The labels inside each plot panel are now done with GCHDRW which draws the characters rather than using PostScript character fonts. These plot files will not be as easy to change as a consequence, but they look much better. Changed PLOTC to support the color option in ELINT. Moved nowhere. 15433. December 9, 2019 APROPO Eric The APROPO was slavish in its use of VERSION. Changed it to be more flexible in AU1A. All it needed was a call to VERMAT. Moved to 31DEC19 this date. 15434. December 13, 2019 KNTR, PCNTR Eric Added adverb PVPLT to NEWPARMS, POPSDAT, PCNTR, and KNTR. It selects a corner of the plot to display a vector of some length in arc seconds whose flux is described in the text line at the bottom of the plot. Wrote subroutines PLTVSZ to decide the corners of the display and the length in asec (from 0.001 to 500) and then PLTVEC to do the actual plot. KNTR and PCNTR will not draw lines of grey scales in the vector box. Moved nowhere. 15435. December 18, 2019 CLIP Eric The PRTLEV test was on 2 of the 3 reports but not the partially flagged report. Added that test. Moved to 31DEC19 this date. 15436. December 26, 2019 AIPSLetter Eric Put back the AIPSLetter LET19B for 31 December 2019. Moved everywhere in $AIPSPUBL. 15437. December 31, 2019 VLA antenna locations Eric Put back the 2019 EVLA.ant.2019 file containing antenna location corrections (and made a new 2020 file for the web). Also put back another dummy VLA.ant.2020 file for VLANT running on pre-2004 VLA data. Moved everywhere in $AIPSTARS. 15438. January 6, 2020 BPEDT, PCEDT Eric Added APARM to the task and help files to allow the specification of the plot ranges in advance. When there are lots of times in a crowded plot, it takes a long time to replot things so this option will speed things up in that case. Changed BPEDIT to implement the option. Moved nowhere. 15439. January 6, 2020 CLIP Eric Added an addition print line for each IF/polarization to show the fraction of samples clipped. It is necessary to count the samples not flagged on input and then to count the samples flagged individually. If the full spectrum gets flagged due to too many channels, the flagged count must be corrected. Moved nowhere. 15439. January 7, 2020 DOVLAMP.001 Amy Expanded the frequencie ranges for band indentification to the widest ranges in the current VLA OSS. Moved nowhere. 15440. January 8, 2020 APCAL Eric Changed: 1. Bug in application when Tant < 0 (never happens these days) used an incorrect subscript. 2. Code to find 10th lowest Tsys found the lowest instead. Fixed the algorithm (loop had to go backwards and then had to branch out). 3. Changed the code to append new solutions to a pre-existing SN table rather than deleting same and writing it anew. 4. Final error message about the lack of source table fluxes Changed the help to discuss the assumption of Trx and Optical depth being independent of IF and to describe the new usage of pre-existing SN tables. The latter will ease the use of APCAL one IF at a time. A comment about source fluxes was also added to the help file. Issues of the quality of fits for Trx amd Optical depth have not been addressed. Moved nowhere. 15441. January 8, 2020 CLCAL Eric The warning about lost data was strengthened because omitted solutions in the SN tables can cause loss of CL table entries. Cannot test for adverb values in those tasks. Moved nowhere. 15442. January 9, 2020 DBCON Eric Changed the maximum number of sources from 2000 to 10000. Moved nowhere. 15442. January 13, 2020 BPFLG Eric Fixed a line in the inputs file that was left over from BPEDT. Moved to 31DEC19 this date. 15443. January 13, 2020 APCAL Eric Added a PLOT OPCODE to plot the model in TRECVR and TAU0 with no model fitting. Moved nowhere. 15444. January 13, 2020 DELZN CLCOR Eric Changed DELZN to add the reference date and its Julian day number to the header line of the output file. Changed CLCOR to look for this and if present to adjust the times by the difference of the input file JD (now found right after the header is read) and the DELZN JD. Moved CLCOR part to 31DEC19 on June 19. 15445. January 17, 2020 Perley calibrator models Eric Created $AIPSTARS/Perley2014.list and 2019.list to list the model file names available from Rick Perley's public ftp site. Changed AU7B (verb CALDIR) to use DATAIN to specify whether Perley 2014 or 2019 models are desired or whether the models shipped with AIPS are desired. Changed CALRD to use VLAOBS rather than BAND (need > 4 characters) and added DATAIN to select a Perley model rather than the shipped models. Fixed up the help files too. Moved nowhere. 15446. January 22, 2020 BPASS Eric One QINIT call was missing the APCORE argument, causing an abort. Moved to 31DEC19 this date. 15447. January 23, 2020 AIPS header Eric Added 3 words to keep track of whether DOCAL, DOBAND, DOPOL have been applied. Will actually count the number of applications. DHDR.INC Added KICCL, KICBP, KICPD DGHEAD Changed to test if Q, U, V are meaing made without any DOPOL (not just right now as before) and to also issue message if doing a DOPOL on top of already having done one or more. Add 1 to the new counters in the header. VHDRIN Added the above to follow KRYPO LSTHDR Added display of Cals applied if present MSGHDR as LSTHDR CATN2L translate 3 more integer words back and forth DKEY.INC add 3 to "normal" keywords VKEY.INC add the 3 as NUMDOCAL, NUMDOBAN, and NUMDOPOL with correct type and pointers. DFUV.INC Add 3 new keywords in K1 array, shift equivalences VFUV.INC Add the 3 keywords with codes and pointers DFIT.INC Add 3 keywords (allowing new one on images too) VFIT.INC Add the keywords, type, and pointers FITLD Change array equivalence to DHDR from 58 to 65 IMLOD As FITLD UVLOD As FITLD CALRD As FITLD GSCAT As FITLD FIT2A As FITLD CONFI As FITLD FPARSE As FITLD PRTTP Print the cal numbers if present in parsed header SPLIT Dropped mysterious setting of all cal adverbs false ahead of the UVGET call that creates the header They were reset to the user's values after but we should test up front to see if the requested calibration can be done. SPLAT As SPLIT Moved nowhere. 15448. January 23, 2020 DENAN Eric NEW TASK: converts any NaNs in a UV data set to 0's with 0 weight. Also 0's excess fluxes. Moved nowhere. 15449. January 24, 2020 Header cals Eric Changed U2IDES in UVUTIL to capture the calibration counts and force them into the output image header for IMAGR, SCIMG, SCMAP. Changed CALIB and FRING to get proper cal counts in the header when writing output single-source calibrated files. Moved nowhere. 15450. January 27, 2020 More cal counters Eric Changed: UVHIM To add copying input cal counters and adding to them appropriately. UVIMG To count the calibrations happening in this task for the output images Moved nowhere 15451. January 27, 2020 FACSET Eric FACSET limited the flux found in models of 3C286, 3C48, 3C147, and 3C138 to rather small radii. Changed the radii to 4 asec for 3C286 and 3 for the others. Significant flux was being omitted in the sum with some models - changing the apparent gain incorrectly. Moved to 31DEC19 this date. 15452. January 28, 2020 more FACSET Eric There are 4 sources useful as calibrators at least at P band when accompanied with a model. These are 3C123, 3C196, 3C295, and 3C380. Added these to FACSET with suitable radii found from Perley 2014 models. Those models do not have components much outside the stated radii, but models coming next will have significant components at larger radii. Moved nowhere. 15453. February 3, 2020 PIPEAIPS Lorant The CALRD change on Jan 17 caused pipeaips to break; fixed. Also took the opportunity to distinguish between IMGTYPE of SIMP versus CONT, the former generating the continuum using the subband averaged data, the latter using the line and averaging on the fly (more accurate but also slower). Moved nowhere. 15454. February 4, 2020 FACSET Eric Added 3C123, 3C196, 3C295, 3C380 with known radii to be used as known calibration sources (mostly at P band). Moved nowhere. 15455. February 4, 2020 EXTLIST Eric GINIT Add comments for SNBLP, SYVSN, BLPLT type numbers AU2A Add these 3, change numbers for ELINT, KNTR, PCNTR, SNPLT, TAPLT AU8A Add sections for SNBLP, SYVSN, BLPLT; change info some for ELINT, KNTR, PCNTR, SNPLT, TAPLT for the EXTLIST verb. KNTR Number adverb words was wrong BLPLT Plot ID number SNBLP Plot ID number SYVSN Plot ID number There are more tasks that should be done. Moved nowhere. 15456. February 4, 2020 help files Eric VLBAEOPS Updated explain info about GSFC web site. SNBLP HELP: removed SNPLT detritus Moved to 31DEC19 this date. 15457. February 5, 2020 Misc Eric VLBAEOPS HELP: updated info about gsfc web location OPTIMIZE.LIS SYSUNIX: make BLPLT not optimized BLPLT Clean up exit section when user hits button D SYVSN Set new plot type in a second place AU8A Fix typo in format. Change test on times being all to <= 0, >= 100 (was <= -10), fixed BLPLT write statement and antennas. Moved nowhere 15458. February 12, 2020 UVDIF Eric Added 2 lines in the summary section. The first gives the actual maximum difference and actual rms difference. The second gives the peak visibility and the visibility at the maximum difference. Moved nowhere. 15459. February 13, 2020 SNFLG Eric The task did not know about X and Y polarizations, jsut R and L. Moved nowhere. 15460. February 19, 2020 BPASS, POSSM Eric Added BPASSPRM(1) < 0 => do a phase only solution. Note that BPASSPRM(4) > 0, set all amplitudes to 1 afetr an A&P solution. POSSM required a change to the self scaling of plots when the range is microscopic. Moved nowhere. 15461. February 28, 2020 UVFIX Eric The differential aberration correction requires the comparison of the apparent position of the source to the apparent position of a point 10 asec North. Since we treat the apparent position as fixed during the run (it actually isn't), we need to do this comparison only once at the same time that we compute the source apparent position. In 31DEC18 and previous, this was done but only for the first source (with the result used for all sources). In 31DEC19 and 31DEC20, the comparison was recomputed every time a source changed which put a time change in the offset position but not the reference position. This made the correction a (false) function of time. Furthermore, when the input file was in B1950, the EPOCH variable did not stay at 2000 for this comparison. This could make the aberation correction a factor of ~200 rather than 0.99992! All these issues have been corrected with the aberation correction now a function of source but not time (except for planets). Moved to 31DEC19 this date. 15462. March 2, 2020 EVAUV Eric The call sequences to QXXPTS and friends did not get changed in this task when they were changed (Feb 1, 2019) for issues with OOSUB. Furthermore, the value of the parameter that tells the Q routine to add or subtract in the DFT was set to add rather than subtract and needs now to be in a slightly different place in the AP memory. Moved to 31DEC19 2 March 15463. March 2, 2020 3D CC tables Eric Changed: PUVD.INC Raised MAXCCC to 8. CCMINI Added a new column 4 but allow NCOL 3, 4, 7, or 8 with column 4 omitted on 3 and 7. TABCCM Call sequence gets another argument (Z), KOLS equivalence is changed, return all call arguments (as 0) even if missing from table SETGDS TABINI -> CCMINI, force DFT on 3D CC file VISDFT TABINI -> CCMINI/TABCCM, when there is Z column, just put xx, yy, zz into AP VSCDFT As VISDFT VSFDFT As VISDFT GRDCRM TABINI/TABIO -> CCMINI/TABCCM, add test for 3D with error exit. RESCCC Changed TABCCM call seq to read then write Z should it exist TABLEUTIL Changed OTABCC call sequence to match TABCCM CLEAN Changed OTABCC call seq (only a close) QCLEAN Changed OTABCC call seq with dummy ZZ many places. OCCINI always has 3 or 7 columns. PBUTIL Changed OTABCC call seq with ZZ (could be real but probably not) SUMARY Convert TABINI/TABIO to CCMINI/TABCCM with changed call sequence. (Routine is not used.) CCMERG Leave with TABINI since basic TABSRT/TABMRG add code for 4 and 8 columns along with 3/7. CC2IM Change TABCCM call seq (dummy Z) FACES Change TABCCM call seq (dummy Z) IM2CC Change TABCCM call seq (dummy Z) IBLED Change TABCCM call seq, use 3D model if present PRTCC Changed to CCMINI/TABCCM, added branch to a parallel set of formats for #D CC tables. CCNTR Leave TABINI/TABIO since doing CC and MF Change width pointer if 3D. UVCON Change local version of VISDFT like VISDFT. EVAUV Change local version of VISDFT like VISDFT. CCEDT Change from specific column parameter fetches to use OCCINI and OTABCC. Include Z column in position testing. CCGAU to use OCCINI/OTABCC, die if already extended model, drop CCTSET (OCCINI will init output table) CCRES to use OCCINI/OTABCC, warn if Z column, test if X position is on image CCSEL to use PCCINI/OTABCC, to support extended as well as point CC tables, to retain any Z coordinate. Raisd max components to 1 million. Added summary displays. CCSEL help file: raised max # components CLPLT To use CCMINI/TABCCM. It can do 3D also. CAPLT To use CCMINI/TABCCM. It can do 3D also. VPLOT To use CCMINI/TABCCM. It can do 3D also. APCLN CCINI/TABINI/TABIO -> CCMINI/TABCCM 3 places SDCLN CCINI/TABINI/TABIO -> CCMINI/TABCCM 4 places RSTOR CCINI/TABINI/TABIO -> CCMINI/TABCCM 2 places CCINI/TABIO -> CCMINI/TABCCM for CCMOD, IMFIT, JMFIT, UVFIT, UVGIT, SAD, TVSAD Tasks FITLD, IMLOD, CALRD, and GSCAT retain the use of CCINI for recovery of very old format CC tables. Moved nowhere. 15464. March 2, 2020 MOD3D Eric NEW TASK: reads multiple CC model facets and computes the Dx, Dy, Dz to be multiplied by the U, V, W of the input data set (What VISDFT puts into the AP to do this). Makes a new CC table with a Delata Z column and a sub-image of the first model image. Don't know how useful this will be - perhaps for P band. Moved nowhere. 15465. March 3, 2020 RENUMBER Eric $AIPSUB/RENUMB did not initialize pointers before trying to expand the catalog file and so did a zero divide. Moved to 31DEC19 this date. 15466. March 5, 2020 Memo 117 Eric Updated AIPS Memo 117 for changes to the CC table. Moved everywhere in AIPSPUBL. 15467. March 5, 2020 DOVLAMP Amy CALRD changed adverb designating freq band from BAND to VLAOBS. Updated this in procedure. Moved nowhere. 15468. March 9, 2020 PIPEAIPS Lorant Missed an else statement in fix 15453 (VLAOBS in CALRD). Hope it does the right thing now. Moved nowhere. 15469. March 12, 2020 Memo 117 Eric Changed the PostScript version to get rid of 4 lines that contain $Id:. These cause cvs to update the file daily and ship it all over! Moved nowhere. 15470. March 12, 2020 EXTLIST Eric Changed AU2A (PLGET) and AU8A (EXTLIST) to support tasks: CONPL, PRTAN, BLSUM, ELFIT, SNFIT, PANEL, PCHIS. Changed all to use their new plot numbers. Also GINIT to ducument the new task numbers. Additional changes: CONPL Drop unused adverb USERID form Fortran and help. PRTAN Changed to count "OUT" antennas separately when plotting, changed to offer the option of plot symbols without numbers. Adverb defaults filled in before plot file creation. Help changed for SYMBOL. BLSUM Changed to plot and print the intensity weighted centroid and number of pixels SNFIT Corrected the number of adverb words. PANEL Put defaults back into adverb values and set XDOPLOT to the current plot type. PCHIS Changed the meaning of the adverbs (APARM(1) and (2) were overriden by the task) and changed the task to fill in the values used including for EXTLIST the average and rms. Moved nowhere. 15471. March 14, 2020 VISDFT Eric Added protections against reading records off the end of the CC tables. This should not happen but has been reported from LPCAL. Perhaps that task doesn't set up all the pointers correctly? That should have been a problem before however although the I/O was changed from TABINI/TABIO to CCMINI/TABCCM. Moved nowhere. 15472. March 23, 2020 CLIP Eric The counting algorithm counted cross hands too much when they are flagged due to parallel hand fluxes. Moved to 31DEC19 25 March. 15473. March 25, 2020 Edit options Eric Changed INQFLT and INQINT to allow fewer than the max number of numbers to be entered. Changed QEDIUTIL and BPEDIT to take advantage of this in a number of the options - most notably the ENTER OTHER ANT function. Changed 10 HLPEDI*.HLP run time documentation files to describe the new functionality. Moved nowhere. 15474. April 2, 2020 XGAUS et al Eric Changed XGAUS, AGAUS, ZEMAN, ZAMAN, RMFIT FOR: 1. Display the type and extrema of the visibble image in image editing window. 2. Correct "PIX FIT" to "PIX_FIT" keyword 3. Do not change the llist of components currently being fit when generating the next initial guess. 4. Correct the array for fit types and the data reading array to MAXGAU rather than 4. 5. In the editing window, add option RESET WINDOW to reset and redisplay the current image in full size. 6. Reanme OFFX to CENTER. 7. When reading NGAUS values to set test limits, allow the user to enter fewer than the maximum and set those not entered to the value(s) for Gaussian 1. Uses INQFLN to know how many are entered. 8. Initialize the image catalog before replaing the image with a sub-image. 9. CURVALUE starts in the middle of the current image rather than the middle of the screen. 10. REDO ALL now does the full array rather than the current sub-array (user's input BLC and TRC) 11. Make sure the NGAUS in the output table is the maximum component number fit. not the number fit. 12. In ZEMAN, set LLCOMP to match the actual Gaussians in the model and then use LLCOMP to set the correct values in RESULT. Correct the array sent to DLESQR to use 1-N rather than those being fit at the moment. Changed XGINI, ZEINI, RMINI to use keyword "PIX_FIT". The past "PIX FIT" with a blank confuses the FITS input parser. Created INQFLN which is INQFLT but has an extra argument to return the number of numbers entered by the user (including any zeros). Changed explain file section of all 5 tasks to mention RESET WINDOW. Changed all 5 run-time help files to cover all the changed functions. Moved nowhere. 15475. April 3, 2020 UVHOL Eric Added DPARM(8) option for when plotting amplitudes. If set the task finds the peak and the first sidelobe on each side (fitting a parabola to the 3 maxima). The values are printed and plotted. The ratio of the sidelobe on the positive L or M side to that on the negative side in db is printed and plotted. All these for each polarization. Moved nowhere, 15476. April 7, 2020 UVHOL Eric Found bugs in the fitting search for the minima. It seemed to work anyway some times but failed otherwise. Also "db" is meant to be in power so 20*log10(amp) for one moving antenna. So changed the ratio computation. Clarify things in the help file. Moved nowhere. 15477. April 7, 2020 CAPLT, CLPLT Eric When there was only one sample the plot routine exited without closing the data set. The next attempted plot then could not open the data set and so caused a mysterious failure. Correction only to 31DEC19 this date. 15478. April 7, 2020 XGAUS et al Eric Changed the error message when no valid pixels are found. If the sub-image is currently chosen, then the message will now suggest doing a RESET WINDOW. Done in XGAUS, AGAUS, ZEMAN, ZAMAN, and RMFIT. Added option to label the step wedge with appropriate intensity information. Moved nowhere. 15479. April 8, 2020 CAPLT, CLPLT Eric Corrected it to compute the model (when requested) as part of setting the max/min of each sub-plot and then to plot one-point models as an X. Multi-point models are connected lines. Moved this additional correction tot 31DEC19 this date. 15480. April 13, 2020 VISDFT Eric When using more than 1 CC file and not the maximum version, the revised code (for 3D CC files) could open the wrong CC file version - the highest rather than the desired one. A 1 character fix. Moved nowhere. 15481. April 15, 2020 FUDGE Eric Corrected the declaration of DESEL from integer to logical in FGCNT, FUDGE, UVHIM, XYMOD, and UVHGM. The way that it was used in these tasks means that it worked correctly despite the error (so no patch). Moved nowhere. 15482. April 16, 2020 UVRMS Eric NEW TASK: Averages all included data in SOLINT intervals and then does statistical analysis of that set of numbers. A histogram plot may be generated as well. The full range of calibation adverbs are available to control which data are included in the average. Added a second plot of the values versus time as an option. Moved nowhere. 15483. April 16, 2020 UVHGM Eric In studying the histogram computation and plotting for UVRMS I found that it treated the edge bins differently so they effectively were only half as wide. Corrected the computation of the histogram and how it is plotted, Moved nowhere. 15484. April 17, 2020 UVRMS Eric Corrected the task to do a proper vector average over the channels and IFs in each visibility. Added DOWEGHT adverb which when > 0 causes the average over baselines and SOLINT to continue to use the weights. Otherwise each baseline and time gets the same weight. The conversion to amplitude and phase is only done after the real and imaginary parts are averaged over the baselines and times included. Added OPTYPE to do scalar amplitude over baselines and times from the vector average over channels and IFs. Moved nowhere. 15485. April 20, 2020 Histograms Eric Changed: IMEAN Adjusted the histogram computation so that the edge boxes have the same width as the others (instead of only half) TAPLT Histogram was okay. Changed to plot connected lines on histograms and binned plots if FACTOR < 0 and to let FACTOR apply to all plots. Also help file. TVHLD Top point was allowed to fall off the histogram. PFPL3 Corrected computation of histogram, added IO error test generalized the size of the histogram with adverb NBOXES Help file too PCHIS Slight adjustment of the edge cases in the histogram. Moved nowhere. 15486. April 21, 2020 VLAEOPS Eric VLBAUTIL.001 had an error on the curl function in VLBAEOPS. curl requires the output to be directed via the "> path/file" construct which was not corrected for the change in GSFC address. Moved to 31DEC19 this date. 15487. April 23, 2020 SPRMS Eric NEW TASK: plots the mean and standard deviation of the spectrum of all included UV data. It can mix sources, baselines, etc if requested. UVRMS: added APARM to control time plot display range and cleaned up a little. Moved nowhere. 15488. April 29, 2020 CookBook Eric Changed 4 Perley models in CALDIR, CALRD and MOD3D. Also RFLAG plot size which confused the pdf version 6 PVPLOT, UVRMS, SPRMS 9 APCAL PLOT, UVRMS, SPRMS V UVHOL fit option: new figure for UVHOL 13 Update 7 ABOUT files Moved everywhere in TEXT/PUBL. 15489. April 30, 2020 EXTLIST UVRMS SPRMS Eric Changed SPRMS To have plot code 68, to set values back in advrebs for EXTLIST. Added UVRANGE also help of course UVRMS As SPRMS code 67 AU2A Added UVRMS, SPRMS to PLGET AU8A Added UVRMS, SPRMS to EXTLIST GINIT Updated the comments Moved nowhere. 15490. April 30, 2020 DO3COLOR Eric Is the correct spelling of this adverb. Fixed help files for ANBPL, BLPLT, BPEDT. BPLOT, EDITA, EDITR, ELFIT, ELINT, GCPLT, PCEDT, PCPLT, PLOTC, SNBLP, SNEDT, SNIFS, SNPLT, SYVSN, TARPL, UVHOL, UVPLT, VPLOT. Moved DO3COL.HLP to DO3COLOR.HLP. Moved nowhere. 15491. May 1, 2020 HELP files Eric I discovered that there were POPS symbols with no help file. Two (MGAUSS, PGAUSS) are not used anywhere so I will not make a null file for them. The other new helpfiles are for DOCLIP, FREQSEL, GR2CHAN, MAXVERS, NSKIP, PVPLOT, REFREQ, SEPCFLUX, TV2CHAN, XYPHASE, and OKCOLORS. Changed existing files: OFFHUINT is a procedure not a verb PLAYR had a total bogus one-liner POPSDAT OKCOLORS had an incorrect color for line type 1 which should normally be the same as tyype 9. Moved nowhere. 15492. May 4, 2020 CookBook Eric The new help files meant changes to the tab completion file HLPIT.LIS. Also ABOUT files ADVERB, ANALYSIS, CALIBRAT, CATALOG, EDITING, HARDCOPY, INTERACT, OOP, PLOT, PROCEDUR, SPECTRAL, TASK, TV, TV-APPL, UV, VERB, and VLBI. This then changed CookBook chapter 13 which then altered the index files (I, J) and table of contents. A typo was also fixed in Chapters 9 and V. The RECIPE file was also changed. Moved nowhere. 15493. May 6, 2020 XGAUS et al Eric Changed: XGAUS Round up number lines in menu, defend plot range when no valid pixels found AGAUS As XGAUS ZEMAN Defend plot range, extra title line in edit menu when an image is visible ZAMAN As ZEMAN RMFIT Defend plot range, correct computation of number of rows and columns in edit menu. Moved nowhere. 15494. May 6, 2020 AIPS MEMos 118 and 122 Eric 118: Recompute edit menu figures correcting captions to match. Add to edit menu tables. Shift colors. 122: Add to menu edit tables. Recompute edit menu figures. Moved everywhere in $AIPSPUBL. 15495. May 7, 2020 TRUEP Eric Added a message giving the ref antenna and estimated angle. Moved nowhere. 15496. May 7, 2020 VLBARUN Eric A variable was reused and then the old value needed when DOPLOT=2 (vast number of plots). A second place used i when ii was set. I suspect I never tested this mode since I did not want all the extra. Moved to 31DEC19 this date, 15497. May 28. 2020 PDPLT Eric NEW TASK to plot PD (spectral D terms) to compare multiple antennas from up to two PD tables. The labeling in color required new routines listed below. Moved nowhere. 15498. May 28, 2020 TV changes Eric This will make the 31DEC20 TV incompatible with the 31DEC19 TV! G3CHAR new to plot characters in color YCHRW call sequence intensity to pass to XAS IMCHAR pass MAXINT in calls to YCHDRW IM3CHR new - IMANOT with intensity passed in XAS Changed character writing so that first 4 bytes of data are the intensity to use, then the characters Moved nowhere. 15499. June 1, 2020 PDPLT Eric Changed AU2A for PDPLT verb PLGET and AU8A for PDPLT EXTLIST. Changed to PDPLT to have its plot type number, to make sure all adverbs have defaults filled in, and to write more than one line of antenna numbers if needed. Moved nowhere. 15500. June 3, 2020 PDPLT Eric Changed PDPLT to allow up to 4 PD tables from up to 4 data sets. A lot of internal array structures and logic changed but in fact things are likely simpler now. Changed AU2A (PLGET) and AU8A (EXTLIST) for this change. The latter will - for the heck of it - support the current version and the previous (2 data set) version. Moved nowhere. 15501. June 10, 2020 RLDLY Eric There was a statement that should have kept higher numbered antennas as REFANT from working at all. Changed a second IA1 to IA2. Moved to 31DEC19 this date. 15502. June 11, 2020 TRUEP Eric Added history writing at 2 levels. Changed help for that. Moved nowhere. 15503. June 12, 2020 PRTSY Eric Task was updated for the change in call sequence when the SY table format acquired a new column, but the sort column was not updated from 4 to 5. Moved to 31DEC19 this date. 15504. June 15 & 17, 2020 PDPLT Eric Changed it to allow different antenna numbers in the different data sets to go together. Also allowed all antennas in one subscript to have the same color with color changing with the subscript in ANTENNAS. Corrected to deal with antennas not having any valid data. Moved nowhere. 15505. June 18, 2020 fix_aips_macos Eric New name for fix_aips_elcap since the issue it corrects affects all Mac OS >= 10.11. Changed install.pl. Web guide install.shtml Moved nowhere. 15506. June 18, 2020 TARPL Eric Changed it to use 1.0 for all RPARM if both RPARM and VPARM are completely 0. Otherwise no data are plotted on this easy user error. Fixed typo in help and added rparm default. Moved nowhere. 15507. June 18, 2020 CLCOR Eric CLCOR in EOPS mode was able to recognize that all groups are identical. But it used the total number of CT table records rather than just the number in the first (real) group. That ended up with spline failures and perhaps aborts. Moved to 31DEC19 June 19. 15508. June 19, 2020 RMTFC Eric NEW TASK: Reads the rotation measure transfer function from a text file as written by TARS. It then convolves the RMTF with a model and writes out a text file in the TARS output format suitable for plotting. Fixed the plotting of the lines at value 0.0 in TARPL. Moved nowhere. 15509. June 19, 2020 PRTSY Eric The previous fix (June 12) meant it could no longer function on old SY tables. Fixed it to find the ANTENNA column in either new or old format. Moved to 31DEC19 this date. 15510. June 25, 2020 PDPLT Eric Drop the IFs line when both APARM(3) and APARM(4) are > 0. Moved nowhere. 15511. June 26, 2020 MTARS Eric NEW TASK to write a text file for input to TARS with up to 9999 model components each with Q and U (at 1 GHz), spectral index, rotation measure, and rotation measure "thickness". It lists the model as comments at the start of the output text file. Moved nowhere. 15512. June 26, 2020 TARS, TARPL Eric TARS: Changed to pass on any comments read from the input file and to add comments showing input APARM(3-10), NITER, and FWHM of the restoring Gaussian. Added option to fit the beam to the amplitude of the RMTF rather than the real part of the RMTF. TARS: HELP changed APARM(9) for above TARPL: Added ability to plot the input text files to TARS as well as the output files. When plotting the output files to set the max/min plot ranges only for those groups that will actually be plotted. Gave it a plot file type number of its own TARPL: HELP changed to show plotting input as well as output text files. Moved nowhere. 15513. June 26, 2020 PDPLT Eric Changed to omit the IF line when both APARM(3) and APARM(4) are greater than zero. The plot program used the number of antennas with data as the upper limit for antenna number lookup table. Changed it to use 50 which is the actual array size limit. Moved nowhere. 15514. June 29, 2020 OMFIT Eric Thanks to diligent work by Ming Zhang (Xinjiang Astronomical Observatory of Chinese Academy of Sciences) a FORMAT statement with a / in it was found. This is an end of line indicator and so cannot be used with writing to a character string for I/O using ZTXIO. Further examination found two more similar usages with multiple /'s in each format. I wonder why this has not cropped up before. Moved to 31DEC19 this date. 15515. June 29, 2020 MTARS, TARPL Eric Changed MTARS Fortran and help to allow each model component to have its own tye. Changed TARPL help to document APARM(8) which chooses wavelength squared over frequency when lotting input text files. Moved nowhere. 15516. June 30, 2020 SPLIT, SPLAT Eric In order to count vis over subarrays when SUBARRAY=0, these tasks turned off DOCAL, DOBAND, and DOPOL. But this meant that these actions would not be counted or tested in DGHEAD and so not appear in the output header. So, erroneously, I commented out the lines turning off the cal adverbs. This then caused SUBARRAY=0 to fail. Restored the turning off and added the code from DGHEAD to make the headers come out ok. Moved nowhere - this is a 31DEC20 bug. 15517. June 30, 2020 PDPLT, TARPL Eric Changed AU2A (PLGET) and AU8A (EXTLIST) to support the latest incarnation of PDPLT and newly numbered TARPL. Changed TARPL to make sure adverbs are properly set for EXTLIST. Changed PDPLT to make sure adverbs set for EXTLIST and corrected logic on deciding what antennas to plot. Zeros mislead the old logic. Moved nowhere. 15518. July 2, 2020 AIPSLetter Eric Put the 30June 2020 AIPSLetter in $AIPSPUBL - LET20A TEX, PS, and PDF files. Moved everywhere in $AIPSPUBL. 15519. July 6, 2020 HOLOG Eric Changed the math for reference pointing. Moved nowhere, 15520. July 6, 2020 FTARS Eric NEW TASK: Version of RMFIT to process a single Q/U spectrum input to and output from TARS. Moved nowhere. 15521. July
