Dear Madam/Sir,

I had a problem while working with VLBA experiment BH222E in aips. This
experiment has a high spectral sensitivity. It was decided to average the
spectral channels 8 times in the new catalog using the *avspc* task after
loading the data into aips. Next, I tried to use *vlbaccor* procedure but
it didn't not work.

>run vlbautil
>inp vlbaload; DATAIN  'FITS:bh222e.fits
>OUTNAME 'bh222e'; vlbaload; recat

>task 'avspc';  getn 1; outseq 1; docal 2; flagver 0; gainuse 0;
>timerang 0, bif 0; eif 0; stokes '';
>avoption 'SUBS'; channel 8;
>runwait('avspc');

>REFANT  = antnum('LA')

>getn 2; vlbatecr; end   --> have ended successfully
>getn 2; vlbapang; end  --> have ended successfully
>*getn 2; vlbaccor; end *--> ERROR!


The following was written in the messenger:
ACCOR1: Task ACCOR (release of 31DEC21) begins
ACCOR1: Writing to SN table 1
ACCOR1: UVGET: doing no flagging this time
ACCOR1: Not calibrating gains bandpass polarization
ACCOR1: ACRCOR: NO VALID AC DATA FOUND
ACCOR1: ACRCOR: DELETED SN VERSION 1 DUE TO ERROR
ACCOR1: Purports to die of UNNATURAL causes

I tried to use indxr, but it didn't help. Could you please help me to
realise what I have done wrong?

I appreciate your help,
Best regards, Tatiana.
