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 nowhere as yet. 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 nowhere as yet. 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 nowhere as yet. 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 nowhere. 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 nowhere as yet - should go to patch. 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 nowhere. 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 nowhere - should go to patch. 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 nowhere. 15319.
