Task:

FITTP, FITLD, UVLOD, IMLOD

Summary:

This patch fixes a problem that causes some information to be lost from AIPS tables when written to FITS under some circumstances. In particular, frequency group codes should now be preserved in HF tables. This patch should be regarded as essential if you are reducing astrometry or geodesy data and using the CALC/SOLVE package but is only advisory otherwise.

Files:

15APR97/APL/SUB/NOTST/R3DTAB.FOR
15APR97/APL/PGM/NOTST/FITTP.FOR

Fix:

1. Fetch R3DTAB and put it in $APLNOT; fetch FITTP.FOR and put it in $APGNOT.
2. Compile with
   COMRPL $APLNOT/R3DTAB
3. Compile all of the FITS readers/writers with
   COMLNK $APGNOT/FITTP $APGNOT/FITLD $APGNOT/UVLOD $APGNOT/IMLOD

Task:

FILLM

Summary:

This patch fixes a problem when using FILLM on data taken between online revision 20 ('new' format, Jan '88) and 23 (autocorrelations included, Feb '90). FILLM used to have no problem with this, but recent changes in the scaling of visibilities in the online system required a FILLM change that introduced problems when loading data without autocorrelations.

Files:

15APR97/APL/PGM/NOTST/FILLM.FOR

Fix:

1. Fetch FILLM.FOR and put it in $APGNOT
2. COMLNK $APGNOT/FILLM

Task:

Registration

Summary:

The REGISTER script that generates and mails the registration information to NRAO has the wrong date string encoded into it. It has 15OCT96 but should be 15APR97.

Files:

15APR97/SYSTEM/UNIX/INSTALL/REGISTER

Fix:

1. Fetch the file and put it in $INSUNIX prior to registering your site.
2. chmod +x $INSUNIX/REGISTER
3. Run the script when you wish to register:
   $INSUNIX/REGISTER
