Hi Eric,

I am reducing a VLBI dataset that includes Y1 without TSYS attached, I am trying to load a Tsys file that I created with a lot of editing and I am getting weird errors from ANTAB. It could be that my edited Tsys file is triggering the errors, but they are more system errors rather than a "there is something weird with the structure of this file" errors. I have run other tasks without any problems.

My inputs are:
AIPS 1: ANTAB     Task to read amplitude calibration info. into AIPS
AIPS 1: Adverbs     Values                 Comments
AIPS 1: ----------------------------------------------------------------
AIPS 1: INNAME     'BC261E ZOOM'           Input UV file name (name)
AIPS 1: INCLASS    'QBAND'                 Input UV file name (class)
AIPS 1: INSEQ         1                    Input UV file name (seq. #)
AIPS 1: INDISK        1                    Input UV file disk unit #
AIPS 1: CALIN      '/home/thoth/amy/stars/RAqr/VLBA/bc261e.y1.tsys'
AIPS 1: SUBARRAY      0                    Subarray (0=> 1)
AIPS 1:                                    Output table versions:
AIPS 1: TYVER         1                     TY table to update
AIPS 1: GCVER        -1                     GC table to update
AIPS 1: BLVER        -1                     BL table to update
AIPS 1: SPARM      *all ' '                List of stations to ignore
AIPS 1: PRTLEV        0                    Print level (0=>none;
AIPS 1:                                    1=> echo cal. file)
AIPS 1: OFFSET        0                    Increase the scan length of
AIPS 1:                                    each side, minutes

The errors are:
ANTAB1: Task ANTAB  (release of 31DEC25) begins
ANTAB1: ZTXOP2: using translated file name =
ANTAB1: ZTXOP2: /home/thoth/amy/stars/RAqr/VLBA/bc261e.y1.tsys

AIPS 1: TASK QUIT WITHOUT RESUMING ME
AIPS 1: Begin check for any 'standard' scratch files
AIPS 1: Scratch files -- destroyed:    0  still active:    0
AIPS 1: Resumes

Any ideas?

Thanks,

Amy
