I don't know why you say REWAY is not likely to be useful.  I think
it could do useful things, but it is sometimes hard to get it to find
what you need without adding too much variability into the
data weights.  It has lots of options since the "correct" thing to do is
not so obvious.

WTMOD with ANTWT=0 (no abs weight change) and NOISE set to be 1
for good antennas and some factor (e.g. 1/50 deg K) for each bad antenna 
should adjust the weights somewhat.  REWAY at least looks at the data
while this assumes a system temperature which we failed to measure.
