Patches to 31DEC00

You will find patches to known bugs in 31DEC00 here.

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

1. SCMAP and SCIMG fail to handle taper correctly and SCIMG does not average channels and IFs. 2001-01-23
2. FILLM failed to catch Solar mode when it should and asserted that mode sometimes when it shouldn't. 2001-01-26
3. UVCON needed updating to match changes made to the handling of model computation. 2001-02-01

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

Task:

SCMAP, SCIMG

Summary:

SCMAP and SCIMG handle taper in the old way that now causes the images to be smoothed twice (for multi-resolution mode). SCIMG did not average all channels and IFs in the data. SCMAP did not set NBOXES to 1 when the user input 0.

Files:

/31DEC00/Q/PGM/OOP/SCMAP.FOR

Fix:

1. Fetch the files listed above and place them in the corresponding area ($QPGOOP) on your system.
2. COMLNK $QPGOOP/{SCIMG,SCMAP}

Task:

FILLM

Summary:

FILLM took the observing mode (after the first scan) from inside the source name rather than the correct place in the data. This could cause Solar mode to be missed or, if the 9'th character of the source name was S, to be asserted incorrectly. The Tsys values in the latter case would be odd (1.0 on calibrators) and the cal to source ratios would be bad. One can avoid the problem by setting APARM(2) to 32 (in 31DEC00) or 16 (in earlier releases).

Files:

/31DEC00/APL/PGM/NOTST/FILLM.FOR

Fix:

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

Task:

UVCON

Summary:

UVCON has a private version of QXXPTS, one of the basic CC model computation routines. The main version and all data preparation routines were modified in mid-2000 to function better on parallel computers but the UVCON version has only been updated now.

Files:

/31DEC00/Q/PGM/NOTST/UVCON.FOR

Fix:

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

Task:

PBCOR

Summary:

PBCOR will not handle data cubes properly due to an error in the scaling of parameters by the low-level subroutine that computes the correction.

File:

/31DEC00/APL/SUB/PBCALC.FOR

Fix:

1. Fetch the file listed above and place it in the corresponding area ($APLSUB) on your system.
2. COMRPL $APLSUB/PBCALC
3. COMLNK $APLPGM/PBCOR
4. COMLNK $APGNOT/{FACES,SETFC,PATGN}

Task:

FRING

Summary:

FRING will not handle irregularly sampled data due to an error in computing memory pointers.

File:

/31DEC00/Q/PGM/NOTST/FRING.FOR

Fix:

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