Hello,
I am attempting to calibrate some archival HI spectral line observations from program AC320 (acquired 1992). These particular data have two FQIDs, but only acquired calibrator information in one (see LISTR scan output below). I have successfully calibrated and imaged the target source "CD1", which was observed in FQID #1. I have so far been unable to successfully calibrate the data in the second FQID. In the documentation for CLCAL I see that it is recommended to run CLCAL once per FREQID; when trying this I get failure messages due to lack of calibrator data in that setup. I assume that somehow I need to copy the calibration solutions from FQID #1 to #2, but I am unsure how to do so.
Any help would be appreciated!
Many thanks,
John
