Are thes VLA data?  If you load the data with FILLM using standard
adverbs then the weights reflect the system temperatures as measured.
Then if you use DOCAL=2 throughout, the weights will be calibrated by
the flux calibration.  This means that when imaging the correct
weights (1/sigma**2) will be used.  If you average data in say UVAVG,
the wieghts will be adjusted accordingly.  We work hard to get you
correct weights throughout.
