Patches to 31DEC15

You will find patches to known bugs in 31DEC15 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 31DEC12 and may be downloaded using a 31DEC13 "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.

The remainder of this document is comprised of the patch descriptions pointed to by the above references.

Task:

GC

Summary: tables used to allow 200 values of gain curve (and Y values) per polarization per IF per antenna. Such a large size is not needed. Unfortunately, some correlators use this maximum even though only a few non-blank values are written. Restored the limit of 200 rather than the reduced limit of 120. The compile list was corrected on 2016-01-15.

Fix:

1. Fetch the files listed above and place them in the corresponding area ($INC and your work area, respectively) on your system.
2. source PGCV.COMP

Task:

PBEAM

Summary: has the option of adding right polarization and left polarization data to make a single I polarization solution. The scaling of the data was incorrect in this mode. Also the format to tell what scaling was used was inadequate.

Fix:

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

Task:

DBCON

Summary: copied flagged table rows as if they were good rows. Changed to drop any flagged rows completely.

Fix:

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

Task:

DTSUM

Summary: did not pick up the second antenna and subarray numbers correctly from the new UV internal format. As a consequence, all samples were counted as one.

Files:

/31DEC15/APL/PGM/OOP/DTSUM.FOR

Fix:

1. Fetch the file listed above and place it in the corresponding area ($APGOOP) on your system.
2. COMLNK $APGOOP/DTSUM

Documentor:

Task:

PCAL

Summary: did not pick up the second antenna number correctly from the new internal format when selecting the data. It is not clesr to me that it could have found solutions.

Files:

/31DEC15/Q/PGM/NOTST/PCAL.FOR

Fix:

1. Fetch the file listed above and place it in the corresponding area ($QPGNOT) on your system.
2. COMLNK $QPGNOT/PCAL.FOR

Documentor:

Date:

Task:

PCAL

Summary: lost the Faraday Rotation calibration when copying each IF to a scratch file for channel-dependent solutions. It also took flagging of a sample too seriously and quit when it could have gone on simply ignoring the flagged sample. GRDSUB needed to defend itself against bad grid- and work-file pointers.

/31DEC15/Q/SUB/NOTST/GRDSUB.FOR

/31DEC15/Q/SUB/NOTST/GRDSUB.SRT

Fix:

1. Fetch the files listed above and place them in the corresponding areas ($QPGNOT, $QNOT, and your working directory ) on your system.
2. COMRPL $QNOT/GRDSUB

Task:

IMAGR

Summary: was able to do auto-boxing only over X values less than the Y image size. No problem if Y is greater than or equal to X, but boxes were only found in left half or quarter or ... of the image when IMSIZE(2) < IMSIZE(1)

Files:

/31DEC15/Q/SUB/OOP/QCLEAN.FOR

Fix:

1. Fetch the file listed above and place it in the corresponding area ($QOOP) on your system. ,li> COMRPL $QOOP/QCLEAN

Task:

OOP

Summary: editing (tasks EDITA and SNEDT) made no flags if the source number in the table was zero which happens sometimes.

Task:

UVFIX

Summary: was supposed to scale the physical values of the projected baseline into wavelengths at the header frequency. Instead, it used the actual frequency of the data sample. AIPS usually has the header matching that of the first IF making this error negligable, but other situations may arise.

Files:

/31DEC15/APL/PGM/NOTST/UVFIX.FOR

Fix:

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

Task:

OOSUB

Summary: and other model subtraction or division tasks (e.g. CALIB) could get the scaling of U,V,W between channels wrong when handling a number of models (facets, frequencies).

Task:

UVLOD, FITLD

Summary: have to convert the old BASELINE random parameter encoding to the modern 3 random parameters. The round-up used for subarray was too small to get the correct result.

/31DEC15/APL/PGM/NOTST/FITLD.FOR

Task:

FITLD, UVLOD
