I can look at the vlbafix question also - but I have noticed something.
If one sets DOWEIGHT=-1 in FITLD the autocorr data have values 10^5 less
while the cross corrs are the same. The weights are changed by 10^6 and
the weight scale code is very simple. I do not understand and am
debugging. I think somehow this affects old VLBA data not recent or I
would have had lots of complaints - including in my own data reductions
