[daip] APCAL error

[Arnaud Collioud]

Dear AIPS developers,

I am processing the session RDV84 (Dec 2010) with 31DEC11 AIPS version. I am trying to build SN tables from GC and TY tables  (5 subarrays), but I am encountering an error with the task APCAL (see below).

APCAL1: Task APCAL  (release of 31DEC11) begins
APCAL1: Writing SN table  1
PCAL1: AMPCAL: NO GAIN FOR ANT:   3 POL: 1 IF:    3
APCAL1: Purports to die of UNNATURAL causes
APCAL1: localhos 31DEC11 TST: Cpu=      0.2  Real=      0  IO=        15
APCAL1: Task APCAL  (release of 31DEC11) begins
APCAL1: Writing SN table  2
APCAL1: AMPCAL: NO GAIN FOR ANT:   3 POL: 1 IF:    3
APCAL1: Purports to die of UNNATURAL causes
APCAL1: localhos 31DEC11 TST: Cpu=      0.2  Real=      1  IO=        15
APCAL1: Task APCAL  (release of 31DEC11) begins
APCAL1: Writing SN table  3
APCAL1: AMPCAL: NO GAIN FOR ANT:   3 POL: 1 IF:    3
APCAL1: Purports to die of UNNATURAL causes
APCAL1: localhos 31DEC11 TST: Cpu=      0.1  Real=      0  IO=        11
APCAL1: Task APCAL  (release of 31DEC11) begins
APCAL1: Writing SN table  4
APCAL1: AMPCAL: NO GAIN FOR ANT:   3 POL: 1 IF:    3
APCAL1: Purports to die of UNNATURAL causes
APCAL1: localhos 31DEC11 TST: Cpu=      0.1  Real=      0  IO=         5
APCAL1: Task APCAL  (release of 31DEC11) begins
APCAL1: Writing SN table  5
APCAL1: AMPCAL: NO GAIN FOR ANT:   6 POL: 1 IF:    1
APCAL1: Purports to die of UNNATURAL causes
APCAL1: localhos 31DEC11 TST: Cpu=      0.0  Real=      0  IO=         1

This problem only occurs for  the X-band and not for the S-band, where APCAL runs smoothly.

Data was imported with FITLD, then processed with VLBAFIX with subarrays determination. GC and TY tables were filled with the task ANTAB.
Maybe something went wrong during ANTAB (even if I have no error message), but I do not know what (and I tried several times).

If you have any clue of what happened...

Thank you!
Best regards,
Arnaud
