[daip] CALIB with a model

Hi,
I am trying to calibrate P-band VLA data with 3C286 as the phase calibrator
and Virgo A as the band pass and flux calibrator. Even though 3C286 is as
good as being a point source at this frequency, the primary beam contains a
few contaminating sources. So I did the bandpass and flux calibration using
Virgo A and made hybrid maps of 3C286 (from a single-source file) comprising
123 facets. As the next step, I'd like to calibrate the phases and amplitudes
of 3C286 (in the primary multi-source file) from this derived model
containing 123 subfields in CALIB, so that I can use 3C286 as the
phase-calibrator in order to map the target source. I tried two different
things (the input parameters for CALIB and the output messages created in
both the cases are pasted below):
One was to let SETJY calculate the flux-density (optype 'CALC') from the known
spectrum. Please note the FACSET messages. It finds only 17 mJy in the model.
I also tried inserting in SETJY the sum of all CC's in the model (~48 Jy)
using the adverb ZEROSP but the FACSET results remain the same. On changing
NMAPS from 123 to 50 results in "FACSET: 0.000000 Jy found from 971
components". Why is this the case? The same exercise with Virgo A (inserting
in SETJY the sum of the CCs from the model) and using the FITS file from
http://lwa.nrl.navy.mil/tutorial/omodels.html works just fine. FACSET finds
the right flux density.
The second was to set the flux-density of 3C286 in SETJY to zero. As far as I
know, the scaling is meaningless in the case the source flux is found to be
zero in the SU table. But FACSET reports the correct flux density in this
case. Also the intensity vs. uv distance plot after applying the calibration
looks reasonably good and similar to the model visibilities. Is this
technique correct then (as long as one doesn't use GETJY after this)?
An easier method is to copy the last SN table produced in the course of
self-calibration and use Virgo A as the primary calibrator to bootstrap the
flux-density of 3C286 in GETJY (flux in the SU table before GETJY is anything
but zero). But I have datasets where 3C286 is the only calibrator in which
case there doesn't seem to be any other choice but to use the maps in CALIB.
Any help on this would be appreciated.
Best regards,
