New Ticket: Polarisation handling broken for VLBA data?

Hi AIPS-ers,

One or the other midnight job between now and approximately 1 week ago has broken AIPS for VLBA data for me.  I suspect it is the one from Sunday, which apparently included a bunch of updates to the FQ table.  Now if I try to run e.g. FRING on some VLBA data, I get:

dop235> FRING1: Task FRING  (release of 31DEC12) begins
dop235> FRING1: UVGET: doing no flagging this time
dop235> FRING1: WARNING: uncalibrated linear polarization data may be a problem
dop235> FRING1: WARNING: uncalibrated linear polarization data may be a problem
dop235> FRING1: Selecting the data
dop235> FRING1: ZCREAT: INVALID BYTE REQUEST =       -7164
dop235> FRING1: SCREAT: DISK  1 ERROR    4 ON SCRATCH CREATE
dop235> FRING1: SCREAT: FAILED TO CREATE REQUESTED SCRATCH FILE
dop235> FRING1: CALCOP: ERROR     5 CREATING SCRATCH FILE
dop235> FRING1: Purports to die of UNNATURAL causes
dop235> FRING1: dop235 31DEC12 TST: Cpu=      0.2  Real=      0  IO=        18

The byte number varies from file to file, but the outcome is the same: no go.

An example file is in ~adeller/tempididata/VLBA_BD161C7_bd161c7_BIN0_SRC00_0_120525T211652.idifits

I can't see where it is getting the idea about linear polarisation from - the AN table says circular and the FQ table says nothing.  Maybe FITLD needs to put some extra info into the FQ table and it hasn't?

Cheers,
Adam
