Hi Amy (et al.)
I tried running the new VLBAPCOR on a scan that was missing
PC information for antenna 10 (Saint Croix). It had worked
fine on a scan that had all the antenas, but the FRING failed
when I tried running on the scan that was missing some PC
information. I can confirm that antenna 10 was there and
showed good fringes in POSSM. Here are my inputs:
AIPS 1: VLBAPCOR: Procedure to correct instrumental phases
AIPS 1: Adverbs Values Comments
AIPS 1: ----------------------------------------------------------------
AIPS 1: INNAME 'BU020B-CBAND' Input UV file name (name)
AIPS 1: INCLASS 'FXPOL ' Input UV file name (class)
AIPS 1: INSEQ 1 Input UV file name (seq. #)
AIPS 1: INDISK 3 Input UV file disk unit #
AIPS 1: TIMERANG 0 4 Time range of a calibrator
AIPS 1: 6 0 1-4 = start day,hr,min,sec
AIPS 1: 0 4 5-8 = end day,hr,min,sec
AIPS 1: 9 0 MUST BE SPECIFIED
AIPS 1: REFANT 2 Ref. antenna, 0=>the first
AIPS 1: CALSOUR 'J0927+3902 ' Calibrator source name;
AIPS 1: *rest ' ' blank => any
AIPS 1: GAINUSE 4 CL table to use; 0=>highest
AIPS 1: ADVERBS FOR ANTENNAS NOT
AIPS 1: CONTAINED IN PC TABLE:
AIPS 1: OPCODE 'CALP' 'CALP' if you are missing PC
AIPS 1: information for any antenna;
AIPS 1: otherwise ' '
AIPS 1: ANTENNAS 10 *rest 0 antennas for which manual
AIPS 1: phase corrections should be
AIPS 1: obtained (i.e. they are
AIPS 1: missing from the PC table or
AIPS 1: are the pcals in PC table are
AIPS 1: incorrect).
AIPS 1:
Here is what happened.

I looked at the inputs remaining in FRING, and it says
GAINUSE=5. However, CL #5 is the output of the PCCOR and CLCAL
steps that didn't have anything for antenna 10, so there is
no antenna 10 in the CL table. I think this would have worked
if the FRING had GAINUSE=4, so there's just a slight table-handling
problem.
