Good Day

I have some EVLA spectral line data that I am trying to reduce. I am
mainly following the steps in Annexure B of the cookbook for spectral line
data.

I did all the editing steps and I am working on the calibration steps
right now. I have more that one freqid per source and have 1 flux
calibrator, 1 phase calibrator and one source. I created 1 FG table and 4
additional CL tables (1 for each freqID and each source) for my CH0 data.
I then copied the 1 FG table and the 4 additional CL tables that I created
to the line data.

I now have to calibrate the bandpass for the LINE data, BPASS. I am not
sure which of the parameters are necessary for this task. INNAME will be
my Line data and IN3NAME my CH0 data. CALSOUR will be my flux calibrator
and FLAGVER is set to 1. Do I use DOCALIB -1 or 1 and do I have to do this
for both FREQID  1 and 2 seperately, and do I specify the GAINUSE, and if
I do which CL table do I use - the CL table for the flux calibrator for
FREQID 1 and 2 seperately or not ?


Thank you
