[AIPS] Patches to AIPS 31DEC17 [NRAO]

This page most recently updated on $Date: 2018/12/19 18:32:45 $ (UT)

You will find patches to known bugs in 31DEC17 here.

With previous releases, we did not change the frozen release tar ball; user sites were required to download the text files and do any compilations themselves. But, beginning with 31DEC04, we provide binary releases for which user sites are not required to have compilers. Therefore, we have reversed our policy. These patches have been applied to the official code of 31DEC17 and may be downloaded using a 31DEC17 "Midnight Job". Any tarball taken after the change date listed below will already have the patches applied. Of course, you may still download and compile the files as before.

The following is a list of pointers to the different patches in this document.

  1. Linear polarization handling applied the parallactic angle twice. 2018-01-09
  2. Batch has not worked for some years. 2018-01-16
  3. CALIB would not use SMODEL on multi-source data sets 2018-01-16
  4. UVSUB did not do OPCODE 'MODL' correctly for multiple facets. 2018-01-20
  5. SETJY printed erroneous error bars with the latest 2017 flux scale. 2018-03-01
  6. UVSUB did not do OPCODE 'MODL' correctly; weights came out zero. 2018-03-14
  7. Large gridded models did not allocate sufficient memory. 2018-04-04

Task:
many
Summary: Linear polarization data had the parallactic angle corrected when applying the D terms and then again when converting from linear to Stokes representations. Changed code to detect when DOPOL was set and the input was linear. Then changed other routines to accept the new DOPOL values and to omit the first of the two parallactic angle applications.

Task:
Batch
Summary: jobs work using a sequence of programs - AIPSC, QMNGR, AIPSB - and the last two had bad call sequences to the routine that manages the queue file. This error has been present for many years - I guess people don't use it much or are too polite to complain.

CALIB
Summary: attempted to protect itself from bad combinations of adverbs and thereby refused to honor SMODEL for multi-source data sets even when its usage was properly specified.

Fix:
  1. Fetch the file listed above and place it in the corresponding area ($QPGNOT) on your system.

Summary: When over-writing an existing antenna file in order to update the format, the tasks would fail if the number of IFs exceeded 28. The issue had to do with keywords required by PCAL.

Task:
FITLD
Summary: attempted to detect and correct duplicate frequency IDs - those with identical frequency setups but different FQID numbers. The attempt was a failure due to poor logic and it was not applied to the tables in any case. Corrected the logic, improved the messaging, and added code to correct the tables as well.

Task:
DBAPP
Summary: had an old version of the UV data pointers while modern data have a different version. This led to a very bad mangling of the output data. Issues with testing of times and of antenna file headers were also addressed.

FQUBE
Summary: attempts to copy CG tables from the input to the output. If the input files had no such table, however, it wrote a new table for each input plane. Fixed it to write everything to one table as intended.
Files:

  1. Fetch the file listed above and place it in the corresponding area ($APGNOT) on your system.

Documentor:

Task:
FITLD
Summary: was changed in how it handled ANTNAME particularly when concatenating multiple input files. It has been found that this change does not work properly. The code has been reverted to its state prior to March 2017 and now again ignores ANTNAME when concatenating. The antenna numbers and names in the pre-existing antenna table control those used absolutely.

DOBAND 3
Summary: bandpass interpolation over time still flagged the data whenever one of the two ends of the interpolation was flagged. Changed it to use the good bandpass solution if there is one. Also discovered the the binary version for LNX64 produced wrong answers when optimized. It is now compiled no-optimize.

Summary: used the wrong position angles for 3C48 and 3C147. At low frequencies it interpreted the "not-a-value" (-999) as a real position angle for 3C147. A small change with frequency was added for 3C286 and the computation of error bars was improved.
