[daip] VLBAPCOR error

[Joseph D Gelfand]

Hello,

    I am really sorry to bother you, but I am trying to run VLBAPCOR on a
VLBA dataset which does not have a PC table.  As shown below, I have set
opcode to 'CALP' and specified all nine antennas in the ANTENNAS as shown
below

AIPS 1: VLBAPCOR: Procedure to correct instrumental phases
AIPS 1: Adverbs     Values                 Comments

AIPS 1: OPCODE     'CALP'                  'CALP' if you are missing PC
AIPS 1:                                    information for any antenna;

AIPS 1:               5           6        obtained (i.e. they are
AIPS 1:               7           8        missing from the PC table or
AIPS 1:               9        *rest 0     are the pcals in PC table are
AIPS 1:                                    incorrect).

When I  run vlbapcor, I get the following message:
ADUAE3> PCCOR1: Task PCCOR  (release of 31DEC21) begins
ADUAE3> PCCOR1: No PC table found
ADUAE3> PCCOR1: Purports to die of UNNATURAL causes
ADUAE3> PCCOR1: aduae312-lap 31DEC21 TST: Cpu=       0.0  Real=       0

Which is correct since this dataset has no PC table, as shown in the output

Do you have any suggestions as to how I get around this?  Thanks a lot, and
hope all is well -- Yosi
