December 3, 2018 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 31DEC19 instead of 31DEC18 - also fix dates in install.pl. Moved nowhere. 15277. December 4, 2018 UVHOL, HOLOG Eric Changed UVHOL to also output a comment line labeling the columns of the data output. Changed HOLOG to parse this line and know whether the input data are amplitude and phase or real and imaginary and convert the latter to the former. Added info about this to HOLOG help file. Moved to 31DEC18 this date. 15278. December 4, 2018 TVIEW Eric Corrected the coordinate computation when ROAMing in the reference image. It was failing when the reference image was sub-imaged. Also added code to detect a TV window size change after the menu item is read. This will reload the images in case the user chose to change the window size during the menu interaction. Moved to 31DEC18 this date. 15279. December 4, 2018 OOP routine Eric UVFRQS in UVUTIL.FOR was issuing an error message if ECHAN was 0 or EIF was 0. Changed to issue error messages only when real BCHAN/ECHAN or BIF/EIF values do not accord with the number of points on the axis. Moved to 31DEC18 this date. 15280. December 5, 2018 CLCOR Eric Changed EOPS function to allow many days (100) instead of the previous limit of 10. Changed the interpolation functions which assumed that there were 5 days of values to give instead the correct number of values. Changed the default CLCORP(2) to 25 so that users are less likely to have to pay attention to it. Also expanded the time range o each group by a little to avoid edge issues. Added code to refigure the groups so as not to include data in the interpolation that was not on integer day steps. Moved to 31DEC18 this date. 15281. December 10, 2018 DTSIM Eric The DTERM code was simply wrong. Examining how AIPS calibrates polarization I was able to reverse engineer the linear method. I left the 2nd order code as it was but it is clearly in error. Added words to encourage LINPOL. Moved to 31DEC18 this date. 15282. December 11, 2018 SNBLP Eric NEW TASK: does SNPLT but plots the baseline-based values from the SN or CL table. Thus it looks for big jumps in the calibration values that would be applied to the data. This is the initial basis of the task SNFLG. It differences phase, delay, and rate and multiplies amplitude gains. Also changed SNPLT to inform the user when IFRA mode is changed to IFDF. Changed also to allow IFRA for PSYS (Tsys from an SY table). Moved to 31DEC18 this date. 15283. December 14, 2018 DTSIM Eric Restored Athol's nearly correct code for DTERM and parallactic angle application. The latter must be done even if the D terms are zero. Added option to "correct" for parallactic angle, like CLCOR. The default does the correction but one may suppress it. Changed DTPM.INC for the new parameter plus DTSIM for the old dterm code and new option and the help for the new option and to remove the deprecation of non LINPOL. Moved to 31DEC18 this date. 15284. December 18, 2018 LISTR Eric Added DPARM(1)=20 to display azimuth in GAIN listings. Moved to 31DEC18 this date. 15285. December 19, 2018 CLCOR Eric My recent "fix" caused EOPS to fail if the observations are recent. The USNO EOP file gives the most recent date of real data as opposed to predictions. CLCOR requires the reqested data all to be "real". Therefire CLCORP(2) becoming 25 causes failures when reducing real data. CLCORP(1) < 0 is also bad since code assumes it is positive and the subtracts it. Changed the default handling and fixed a failure to close the file on error. Moved to 31DEC18 this date. 15286. December 21, 2018 large BP tables Eric Changed BPASS to allow up to 15000 times. Changed BPEDIT to allow up to 15360 colors (times). Link BPEDT, PCEDT, PDEDT. Moved to 31DEC18 this date. 15287. December 21, 2018 TLCAL Eric Fix the error message when the telcal file is not found. ZTXOPN gave the full path name but TLCAL itself truncated the the name that it had. Now it will show the full name. Add further comments about DOAPPLY to the help file - it is a VERY useful option. Moved to 31DEC18 this date. 15288. December 31, 2018 AIPSLetter Eric Put back the AIPSLetter for 31DEC18. A Ps.gz, PDF, and TEX file. The uncompressed PS is really too large. Moved everywhere in TEXT. 15289. December 31, 2018 VLA antenna files Eric The file $AIPSTARS/EVLA.ant.2018 was copied from the analysts web site and installed for use. Moved everywhere in TEXT. 15290. December 31, 2018 VLBAUTIL, VLBARUN Lorant Added parameters EOPSFILE/TECRFILE to VLBARUN to use local copies in case the web site fetch is unsuccessful. Added after Amy already prepared for this in VLBAEOPS/VLBATECR earlier. Moved to 31DEC18 this date. 15291. January 3, 2019 "FLUX" Eric Plot tasks have used the word flux when the correct word is brightness. Changed COMLAB, IAXIS1, GREYS, KNTR, PROFL, and PCNTR. Moved to 31DEC18 this date. 15292. January 18, 2019 VBCAL Eric The task failed to write out any data due to 2 egregious errors made in March 2014. Corrected these and fixed the default values for the FPARM, RPARM, VPARM adverbs. Improved the wording of the help file. Improved the one-liner and mention VBCAL in REAMP help file. Moved to 31DEC18 this date. 15293. January 23, 2019 BPASS Eric Changed to have BPASSPRM(10) = 7 through 10 to do normalization with medians rather than means. 7 and 9 use ICHANSEL, 7 and 8 do phase and amplitude, 9 and 10 do amplitude only. Moved nowhere. 15294. January 30, 2019 models Eric ALGMEM when asked to compute a model simply zeroed the data record except for weights. This is not good when only some of the Stokes are being modeled and when the model depends on frequency so that only certain channels are being done at the time. Fixed the zeroing to do only what is needed. VISDFT does not seem to work however. Moved to 31DEC18 on March 5. 15295. January 31, 2019 UVLOD, FITLD Eric Changed the counters of the number of spectral windows to double precision. Integer could overflow. Added a progress message to UVLOD and the UVLOD part of FITLD. Add percent previously flagged to history. Moved nowhere. 15296. February 1, 2019 OOSUB Eric DFT modeling with multiple frequencies did not work unless all groups had the same number of channels. Found and fixed cause, noticed that 'MODL' would not work if there are so many channels/facets that more than one pass in the UV data were required. That fix and the extended model objects not tested but the one pass and points extensively tested. Changed: OOSUB To allow VISDFT to issue progress messages PBUTIL To not have groups of channels with opposite frequency order (i.e. when AC is overlapped by BD) VISDFT To also send the max number of channels in a group to the Q routines so that they can find the MODL pointer. Since it can read the UV data file in one pass and the accumulated data in a second pass, added code to zero the input UV data on the first pass Change UUU to a scale factor. QXXPTS Added call argument to use to point at the model code. Use that now as a scale to add (modl) or subtract (' ') the model as set by VISDFT. Simplifies inner loop. QGASUB As QXXPTS QSPSUB As QXXPTS QPTDIV Drop unused variable that was some of the cause of all this trouble. Moved to 31DEC18 on March 5. 15297. February 4, 2019 DFT vs GRID Eric Image modeling tasks must choose the more efficient CMETHOD unless the user has specified a method. Routines that decide how many facets/channels may be modeled at once need to know the method as do the ultimate subtraction or division routines. OOSUB was found to be ignorant of essential parameters at the first such decision point. Changed OOSUB to acquire the number of visibilities (not set RRAW mode) and changed FORCED to handle the number of facets <= 0. Moved to 31DEC18 on March 5. 15298. February 6, 2019 TYSMO Eric The clipping parameters (in APARM) were applied when reading the TY or SY table into the arrays to be median-window smoothed. Then the MWF clipping (in CPARM) was applied, but the input data were not checked as well for the initial APARM clip. Corrected this and made 3 counters for each data type - to count the APARM clip, the CPARM clip, and any other samples found blanked in the MWF output. Added info about these numbers to the help file. Added option DOSCALE which requests that the MWF be done normalizing the values in each scan so that CPARM refers to normalized values rather than the values in the ?Y file. Moved to 31DEC18 on March 5. 15299. February 6, 2019 XAS.SHR Eric Added comments to the Makefile for MACINT in case of gcc rather than intel. Adjusted several for modern Macs (X11R6 is disappearing, only X11 directory remains). No need to rebuild XAS however. Moved nowhere. 15300. February 7, 2019 FRING Eric Changed DPARM(9)=0 meaning whenthe array is EVLA. Rates are almost never wanted for the EVLA and so changed DPARM(9)=0 to 1 for EVLA before setting the no-rate flag. This avoids a mistake whose consequences are not obvious to non-VLBI users. Moved nowhere. 15301. February 7, 2019 TYSMO Eric The subroutine that applies flags to the SY table was not updated when the format was changed (to add the column for Solar vs regular). All flagging in TYSMO was wrong. Moved to 31DEC18 March 5. 15302. February 8, 2019 CLCAL Eric The code that fixed up reference antenna <= 0 did not take the IF into account. Fixed to correct all IFs if they need it in the smoothing code. Moved nowhere. 15303. February 11, 2019 POSSM Eric Corrected the text file output of coordinates to include the correct sign of the declination at all times and to use I2.2 type formats. Also fixed the lead character of the seconds. Moved nowhere. 15304. February 11, 2019 PLOTR Eric Changed to allow in-line (trailing) comments. Mention color column (optional) plus in-line copmments in help file. Moved nowhere. 15305. February 12, 2019 CALIB Eric Changed to allow polarization averaging in linear as well as circular polarization types. Moved nowhere. 15306. February 12, 2019 TYSMO Eric Psum was being flagged when Pdif was clipped (by APARM) and then reported mysteriously as flagged. This was due to testing on Psys when no test on Psys was requested. Changed to flag only when Psys testing is done. A wrong counter was used one place. Moved to 31DEC18 March 5. 15307. February 13, 2019 SY table Eric The number of columns is now 13. Fixed TYCOP, PRTSY, VLAMP, and SY2TY. Moved to 31DEC18 this date. 15308. February 14, 2019 SY Table Eric Changed PUVD.INC to include the number of columns and record size parameters for the SY table. perhaps this will help avoid the issues we have ben having. Changed SYINI, SYSEL, TABSY, and tasks PRTSY, SPLAT, SY2TY, SYSOL, TACOP, TYAPL, TYCOP, TYSMO, UVCOP, VLAMP. Also changed TYCOP so that BPARM(1) <= 0 -> replace all IFs. Moved nowhere. 15309. February 26, 2019 OOP Eric OBJMNGR subroutine OBOPEN can fail if all 6 buffers are in use. Changed the error message to tell about the buffers in use and the new one requested. How BPEDT triggered this state is a mystery because the old error message gave no real information. Moved nowhere. 15310. February 27, 2019 XY pol Eric Corrected the sign of the parallactic rotation formulae in converting linear polarizations to Stokes. Moved to 31DEC18 on March 5. 15311. March 5, 2019 planets Eric Wrote subroutines: FNDCOO Finds mean or apparent coordinate of specified source number. If there is a PO table (planet positions), it makes a list of all planet source numbers in the table. If the source is not a planet, it calls GETSOU if needed and returns the requested coordinates. If a planet, it searches the PO table for the closest position in time and returns that, precessing mean to apparent if requested. COOELV A version of SOUELV that takes the coordinates as arguments (returned by FNDCOO) rather than depending on them from the DSOU common. Has error return of both antenna coords are 0. PARACO A version of PARANG that takes RA/DEC as arguments and uses COOELV for Nasmyth mounts POSEL Copies PO table can select and renumber a single source. Does not make empty output files. Changed POINI Source number column has an underscore these days. SOUELV Fix error: it tested the apparent RA and Dec to see if they were less than a tiny positive amount. That test must be on the absolute values! Added error return if antenna coords are both 0. DATPOL Changed to use FNDCOO rather than SOUFIL and then use PARACO to get parallactic angles DATPAR As DATPOL CVLDOP Changed to keep track of the last time and call FNDCOO when time changes, use resulting coordinates to call DOPLR. Other interval management left as it was. TABLEUTIL Subroutine OSUELV: drop GETSOU call, call instead FNDCOO and then call COOELV rather than SOUELV. Changed USUPAN also to call FNDCOO rather than GETSOU and then use PARACO. This changes: CL2HF, INDXR, WFCLN, IMAGR, SDGRD, BSGRD. Tasks (with help files in most cases) ACFIT Replace GETSOU, SOUELV with FNDCOO, COOELV. ANCAL Replace GETSOU, SOUELV with FNDCOO, COOELV. CLCOR Changed to use FNDCOO in 9 separate places almost all of which are followed bu COOELV. Also one place to use FNDCOO followed by PARACO. DFCOR Much like CLCOR FARAD Replaced GETSOU with FNDCOO and do often rather than once HAFIX Help file: comment that planets are not supported LISTR Change GETSOU to FNDCOO, PARANG to PARACO, and SOUELV to COOELV in 2 subroutines. Added DPARM(1)=21 for hour angles. SPLAT Added copy of PO table with or without source selection. SPLIT Added copy of PO table with source selection. SUFIX Add comment to help file that task does not do planets. UVFIX Add FNDCOO to set J2000 and apparent coordinates. The code that computed the rotation of the field for differential aberration computed the parameter only for the first source. Corrected it to compute the parameter every time the source number changes (even using the moving source coordinates). Precession for planets (and other sources) is done here with JPRECL (subroutine in UVFIX) rather than JPRECS to get the differential aberration correct. UVFLG Changed the shadowing algorithm and the elevation algorithm to use FNDCOO and the latter to also use COOELV. The zero fringe rate code does not support planets. VLANT GETSOU replaced with FNDCOO and a local SOUELV and the normal one replaced with COOELV and equivalent. APGPS GETSOU replaced with FNDCOO, SOUELV with COOELV. TECOR GETSOU replaced with FNDCOO, SOUELV with COOELV. PCVEL Local copy of CVLDOP changed as CVLDOP. ANBPL Add FNDCOO, change to COOELV and PARACO APCAL Add FNDCOO, change to COOELV. ELFIT Replace GETSOU with FNDCOO, change ANTGEO to take the coordinates, correct misuse of apparent coordinates (which could have been 0) ELINT Call FNDCOO at all 3 computations of COSZ. SNFIT As ELFIT SNPLT As ELFIT UVPLT Changed to use FNDCOO and COOELV when plotting hour angle, elevation, or azimuth plus FNDCOO and PARACO when plotting parallactic angle. VPLOT Add FNDCOO, change to COOELV and PARACO WIPER As UVPLT Moved nowhere. 15312. March 6, 2019 IM2CC Eric Added IMSIZE to allow each output image to be larger than the input/NX, input/NY. The image size controls the accuracy of gridded modeling and larger is much better. Moved nowhere. 15313. March 7, 2019 MOVE Eric Add OPCODE='COPD' which copies (allowing duplicate names like 'DUPL') and then deletes the input file. Moved nowhere. 15314. March 7, 2019 DOC files Eric HLPIT.LIS add snblp ABOUT files for CALIBRAT, PLOT, TASK, UV. Moved nowhere. 15315. March 12, 2019 CookBook Eric Corrected all figures that metioned "flux" when they should have mentioned "brightness" or something else more suitable. Chapters: 4 Figures, SNBLP, BPASS, TYSMO, FRING, PO table 6 Figures, add TVIEW, SNBLP 7 Figures, IMFIT rms, TVIEW 8 Figures 9 FITLD weights, CLCOR EOPS, SNBLP 13 Numerous ABOUT files over the last 6 months C FITLD weights, CLCOR (EOPS), SNBLP D SNBLP V Figures, UVHOL I update J update 0 update Recipe Rearrange due to recipes pulled to make space Moved nowhere. 15316. March 12, 2019 SPLAT Eric History file did ICHANSEL even when it was not used. Moved nowhere. 15317. March 18, 2019 FACES Eric Added BMAJ < 0 option to have the CC files written as Gaussians rather than points. Moved nowhere. 15318. March 21, 2019 Obsolete things in help Eric Removed obsolete reference in help files, e.g. MX, DDT, PFT, VM, HORUS, and more. Changed help files for APARM APCLN ASTROMET BLCAL BLCHN BPARM BSMAP CALIB CALIBRAT CCFND CHANNEL CMETHOD CXPOLN DBCON DDISK DFTIM DFTPL EDGSKP GUARD HITEXT IM2UV IMAGR IMSCAL IOTAPE LENGTH LINIMAGE LPCAL LSAPROPO MAPDIF MAPPR MAXPIXEL MDISK NCOUNT NMAPS OOCAL OOSRT OPTELL OUT2NAME OUTNAME OUTFILE OUTPRINT POLPLOT PRTAC PRTCC PRTHI REWEIGHT RSTOR SCIMG SCMAP SDCLN SUBSTR TCODE TDISK TELL TMASK TMODE TNAME UTESS UV1TYPE UV2TYPE UV3TYPE UV4TYPE UV5TYPE UV6TYPE UVMAP UVPRM UVSRT UVSUB VLABP VLAL VLBAIT VTESS WFCLN WHATSNEW Y2K ZWEROSP Changed scripts to use IMAGR rather than MX: CXPOLN VLBAIT Rewrote some of CALIBRAT Updated adverb help files with current list of tasks CHANNEL CMETHOD GUARD MAXPIXEL NCOUNT NMAPS OPTELL OUTFILE OUTPRINT POLPLOT REWEIGHT TELL UVnTYPEs ZEROSP Moved to $APLCONTR: DDTLOAD.001 DDTEXEC.001 DDT.HLP DDTSAVE.HLP PFTLOAD.001 PFTEXEC.001 PFT.HLP old vers of DDTSIZE.HLP Moved nowhere. 15319. March 22, 2019 CLCOR Eric EOPS needs to check that the first date in INFILE is before the observations. It did not do this check; it did only the last real data vs that required. With the 500-day usno file making the rounds these days this is significant. Moved nowhere. 15320. March 22, 2019 IMAGR Eric Changed QCLEAN TV code to include the NEXT FIELD and LAST FIELD options when there are too many fields to list them in a menu. Having to type in field numbers is not okay when trying to check every field (facet). Moved nowhere. 15321. March 26, 2019 Misc Eric RFLAG Increased 1 format. IMAGR Changed QCLEAN to do STOP and ALLOW FLD on all values of OVERLAP. My recent change led to a bad menu when OVERLAP 2 switched to OVERLAP 1. Moved nowhere. 15322. March 26, 2019 FILIT Eric FILIT did not test that the input files are MA rather than UV. The interactive session did not set the flag to display the menu and so loaded the images one after the other without doing anything useful. The roam function in TVUTIL.FOR started with image plane 2 rather than the 1 assumed by TVROAM. This caused the LUT of one of the planes not to update properly. Corrected the passing of the image planes used to include all of them. Moved to 31DEC18 on 28 March. 15323. March 28, 2019 CookBook Eric Changed ABOUT files because of the removal of the obsolescent procs and tasks. Changed were ADVERB GENERAL HARDCOPY OBSOLETE POLARIZA PROCEDUR RUN VLBI. Updated the CookBook chapter 13 for these including COOKBOOK.PDF and the html version available from the web. Moved nowhere. 15323. April 2, 2019 ROTMEAS, SPLIT Eric Created adverb ROTMEAS is a help file plus POPSDAT and NEWPARMS. Added the adverb to SPLIT. If it is not zero, SPLIT will do output Stokes either RR/LL/RL/LR or IQUV and will correct the Q/U or RL/LR values for the stated rotation measure. This will allow averaging Q and U over much wider ranges in frequency in the presence of a known rotation measure. The resulting Q and U are those at 0 wavelength (infinite frequency). The rotation measure applied is listed in the output header's keywords. Moved nowhere. 15324. April 3, 2019 TABSRT Eric TABSRT had a hard-coded LUN=89 which conflicts with the same value used when reading the PO table. Changed TABSRT to use LUNTMP(1) to get a unique LUN not currently in use. Moved nowhere - this is a 31DEC19 bug. 15325. April 3, 2019 plot labels Eric Change 15291 worked mostly but there was one hard-coded string length (for plotting) that did not get larger for the change from "flux" to "brightness". Changed COMLAB, PCNTR, KNTR, GREYS to set the length dynamically. Also changed them to allow the LEVS string to be 20 characters longer. Moved to 31DEC18 this date. 15326. April 4, 2019 QCREATE Eric Changed $APLGEN/ZCREAT.FOR to have QCREATE=0 mean do the quick create. If you really do not want it, then QCREATE has to be set to < 0. Changed help files for QCREATE, GO, DOOSRO, and PIPEAIPS. Moved nowhere. 15327. April 10, 2019 OOSUB, EVAUV Eric UVMDIV had the wrong argument to UVDOUT. It was supposed to send the number of channels but sent the highest channel in the group instead. This caused data to be set zero before the data for that group was run. This affected primarily OOSUB in its division mode. EVAUV had similar code that probably has never been invoked. Moved to 31DEC18 this date. 15328. April 24, 2019 CLCOR Eric The call to FNDCOO for PANG had a bad call sequence leading to an abort. Moved nowhere. 15329. April 24, 2019 SNPLT Eric The computation of the second Psys when doing difference or ratio of 2 IFs had an incorrect subscript. Moved nowhere - patch? 15330. May 1, 2019 planet code Eric The call sequence to FNDCOO was not correct in ACFIT, DFCOR, and VLANT. Numerous places assumed that the data (uv or table) were in time order, including places where that is not enforced. Changed ELINT (incl to check on source change), plus FARAD, LISTR, UVFIX, CVLDOP, PCVEL, ANBPL, APCAL, ELFIT,SNFIT, SNPLT. Moved nowhere. 15331. May 2, 2019 EOPS Eric Changed VLBAUTIL.001 for new web site for EOPs. Moved to 31DEC18 this date. 15332. May 3, 2019 SPIXR Eric The FQ axis handling did not do a subimage correctly. Moved to 31DEC18 this date. 15333. May 8, 2019 RESCALE Eric New adverb DOCC in POPSDAT, NEWPARMS, DOCC.HLP to enhance the RESCALE verb. DOCC <= 0 leave CC files alone, DOCC > 0 rescale CC files, DOCC >=2 scale CC files but not the image. Moved nowhere. 15334. May 14, 2019 POPS K array Eric Decided to increase the K array size by a factor of 4 to allow easier development of RUN files such as pipelines. The new code should automatically update existing ME and SG files. Changed: POPSDAT HLP - to force the MNJs to run the new POPSGN POPSGN Added code to check the size of the current memory file and to delete and recreate it if it is too small. PKSZ INC - changed sizes of K and text arrays, pointer for variables in K and the version # (to 17) SGLOCA Changed the array of known sizes and fixed an error: the later routines expect MSIZE to be the sum of the 2 sizes. It used to return the 2 sizes as was. This led to the loss of any procedures and probably made the auto update fail. STORES For pseudo-verb STORE 1, added code to check if the ME file exists and is large enough. If not, the old one is deleted if needed and a new of the new size created. MSGONE New routine to see if the message file for user 1 exists and if not create on but only for AIPS itself. ZDCHIN Added call to MSGONE since ZDCHIN can generate error messages re NETSP and the like. RDUSER Added call to MSGONE. Moved nowhere. 15335. May 29, 2019 AIPS Eric The subroutine CHKCHR was changed to handle error messages from long and bad strings. It had a formatting error with long strings (bigger than MSGTXT. Moved nowhere. 15336. May 29, 2019 FACSET Eric A format failed for more than 999 Jy. Made it larger. Moved nowhere. 15337. May 29, 2019 BDF2AIPS Eric Added DOSTOKES to select the number of Stokes when data contain both 2 and 4 in the same configuration. Changed AUO to support DOSTOKES -> selStoke in OBIT. Updated BDF2AIPS help file. Moved nowhere. 15338. May 29, 2019 TABED Eric Added recommendation of TABPUT to the TABED help file. It is much much easier to use. Moved nowhere. 15339. May 29, 2019 SETJY Eric Created new adverb SRCALIAS(30) to give source name aliases so that the user's name for a source does not have to match the official name(s) of the source for 'CALC'. Changed POPSDAT.HLP, NEWPARMS.001, SETJY.HLP, SETJY.FOR, and made a new SRCALIAS.HLP. Moved nowhere. 15340. June 3, 2019 TABSRT Eric Add protection to not overflow the "AIPS bytes" value. We now allow the pseudo AP to be a bit too large for this. Moved nowhere. 15341. June 5, 2019 RFLAG Eric Added much needed option FPARM(17) to flag all of any channel for which > FPARM(17) of the times are flagged. Moved to 31DEC18 14 June. 15342. June 5, 2019 ITBSRT Eric Improved a format to encompass the full possible range. Moved nowhere. 15343. June 7, 2019 KNTR Eric The plane computation used too large a roundoff and so could get the wrong answer - plotting more planes than there are in the image. Moved to 31DEC18 14 June. 15344. June 10, 2019 UVPRT Eric Added DOACOR to the inputs. One usually is not interested in them and their format can be rather different. Moved nowhere. 15345. June 10, 2019 RFLAG Eric When flagging all times for a channel flagged > FPARM(17) of the time, the task really should use the source number(s). Using 0 for the flags of short duration is fine, but not these new kinds of flags. Fixed it. Moved to 31DEC18 14 June. 15346. June 11, 2019 RFLAG Eric Changed help file to encourage use of FPARM(13) - NaNs can come out at least with one VLBA source if no clipping. Moved to 31DEC18 14 June. 15347. June 12, 2019 VLBA procs Eric VLBAUTIL.001: a) Change the typing to avoid long lines. b) Minor fixes, e.g. END IF is not POPS, changed grammar around use of DEFAULT. c) Fixed messages to use lower case in many items. VLBARUN.001: a) Changed typing to avoid long lines and make the code much more readable. b) Corrected bug associated with TIMER(1) option. c) Changed imaging of line data to do one IF at a time (messy problem to get plots out properly). d) Added "magic" as RHEL 7 version of "convert" to make gif files from eps files. e) changed OUTFILE option to make a directory named by date and time added into which the plots, html, prtmsg goes. d) Added CLRMSG at start, PRTMSG to a file associated with the vlbarun.html file. e) Changed LINE KNTR plots to plot 16 channels stepping through the full range of channels every n'th channel. f) Imaging cell size changed to take highest SPW frequency into account g) The background "color" of the gifs was changed to a light grey by changing that color in LWPLA. h) An option was added to read in a text file of flagging commands to be put in FG table 1. i) An option was added to run RFLAG twice on each source, once with DOPLOT=12 then with DOPLOT=-12. LINE cases do not do the spectral flagging. Fluxes are clipped at 100 Jy in advance of the statistics, channels that are flagged more than 30% of the time are flagged over all time (by source), and 1 channel on each side of a flagged channel is flagged. j) The test on CALSOUR and SOURCES all being in the SU table was moved from the FRING proc (late in the pipeline) to the initial parameter examination proc at the start of the pipeline (after data are available). Moved nowhere. 15348. June 12, 2019 BPWAY, RLCOR, REAMOP, REWGT Eric These tasks rescaled UVW but only for the shift to a center reference pixel. They did not include the changes due to BIF not equal to 1. Moved BPWAY, RLCOR to 31DEC18 14 June. 15349. June 13, 2019 VLBARUN Eric One more change: to have the plots appear two across in the html file when there are multiple plots for a stage of the processing. Also fixed grammar of getdate and added a date and time to the top of the html file. Moved nowhere. 15350. June 13, 2019 BPWAY Eric Added a NORMALIZ option to aoid the rms spectrum normalization if desired. The default will be to do the normalization as the task was originally designed. The changes to REWGT and REAMP yesterday were incorrect and have been rescinded. Moved nowhere. 15351. June 14, 2019 RFLAG Eric The accumulation array is hard to zero and is done carefully when data are found. However, if there are no samples for a particular baseline at some time, the old values can hang around and lead to strange fluxes and extraneous flags. Passed the array that knows what values have been set to the averaging routine so that it can zero the values that were not set. Moved to 31DEC18 this date. 15352. June 14, 2019 VLBARUN Eric POPS always does a for loop at least once. Added a test in the RFLAG procedure to make sure that there are SOURCES before looping on them. The setting of VNUMBER=36-getpopsn requires the = sign to work. Added 2 = signs that were missing. Dropped the test for the existence of vlbarun.html. It should never exist and the test makes a "concerning" error message. Moved nowhere. 15353. June 14, 2019 FGPRT Eric NEW TASK: Prints a count of the flags applying to selected sources, IFs, channels, polarizations in a baseline matrix. Moved nowhere. 15354. June 20, 2019 TAPLT Eric The test for singular axis was backwards so good plots died. Added FACTOR to make bigger plus signs. Moved nowhere --- patch? 15355. June 20, 2019 RFLAG Eric Added FPARM(18) to make an NS table containing NOISE and CUTOFF on a per baseline basis when computing NOISE and SCUTOFF. When doing flagging, if FPARM(18)>0, use the NS table to set clip levels on a per IF per baseline basis. Moved nowhere. 15356. June 20, 2019 VLBARUN Eric 1. DOCAL -> DOCALIB, DOBAN -> DOBAND 2. Add RFLAG plots in living color to html output 3. Change RFLAG clip level to max (100, DOFLAG) to allow for very strong masers. 4. Change to have RFLAG use the per baseline clip levels in FPARM(18). 5. Change IMAGR code to start with DEFAULT IMAGR and then set needed adverbs. 6. Added p_debug for IMAGR 7. Added file name to subject line of e-mails. Moved nowhere. 15357. June 21, 2019 VLBAMPHC, VLBARUN Eric VLBAMPHC is a script to apply calibration from the primary data set to data sets from secondary phase stopping centers. DiFX can correlate at numerous phase stopping positions within the beam. It writes a "primary" data set including the pointing for multiple centers and all non-multiple sources. It also writes data sets for each of the seconday phase stopping centers. This gets around the issue of one array observing multiple sources at the same time. VLBAMPHC copies the calibration (CL, BP) from the primary data set, flags the secondary data set, applies the calibration and makes images. VLBARUN was changed to delete any NS tables on P_RESTART with a number of wording improvements to its help file. Moved nowhere. 15358. June
