Hi,

I'm having an issue calibrating an old (2002) VLBA dataset.  It's a multi-frequency set, which is failing with the error no valid AC data found. when attempting to calibrate with the pipeline VLBARUN, or running the task VLBACCOR.  I'm attaching the specific error message below.  Do you know why this might be?
LOCALH> ACCOR1: Task ACCOR (release of 31DEC18) beginsLOCALH> ACCOR1: Writing to SN table 1LOCALH> ACCOR1: UVGET: doing no flagging this timeLOCALH> ACCOR1: ACRCOR: NO VALID AC DATA FOUNDLOCALH> ACCOR1: ACRCOR: DELETED SN VERSION 1 DUE TO ERRORLOCALH> ACCOR1: Purports to die of UNNATURAL causes
Thanks,
Peter
