Hi!
Suddenly my script running IMAGR and SAD (repeatedly making and feature-finding in image cubes) is failing, and on some files that it previously worked on without problems, and without any changes to any code or data (that I’m aware of).
IMAGR runs OK on the first unflagged channel (channel 110), which is consistent with the requested niter=100...
IMAGR1: Total Clean components 100 reaches limit 100
IMAGR1: Restoring Clean components
IMAGR1: Field 1 final Clean flux 1.576 Jy
... then starts issuing error messages, apparently before finishing that channel... messages that suggest some sort of file problem... maybe a work file problem, because I can run other code on this same source UV file without problems....
IMAGR1: ZDAOPN: DELAY 1
IMAGR1: ZDAOPN: DELAY 2
IMAGR1: ZFI2: DELAY 1
IMAGR1: ZFI2: DELAY 2
IMAGR1: ZFI2: REQUEST FOR BYTES 1 THRU = 1024
IMAGR1: ZFIO: OPER = READ LUN = 16 NREC = 1
IMAGR1: ZFI2: BEYOND EOF = 0
More messages and code and header are further below, but I’m hoping that you know what triggers these messages and can give me a lead on resolving them!
I also pasted in the UV file header, which had odd message when FITS file was originally loaded into AIPS: “FITLD2: WARNING! STOKES VALUES NOT CONVERTED TO NORMAL FORMS” although I don’t think that has anything to do with this problem, because the same code ran on the same file previously.
Thanks,
Bob Gray
