[daip] POSSM model problem

[Craig Walker]

I have encountered a problem, apparently reported before, with
BPASS not producing solutions when dividing by a CC model.  I have
placed the offending data in a special file containing only the
calibrator, along with the tables as they now stand.  The BPASS
inputs are given below. I ran on this subset file and the problem
does occur so it should be good for testing.  The uv file is on
/DATA/PINGORA_3 while the model is on /DATA/PINGORA_2.  If you want
fits files, let me know.  The uv data is pretty well stripped down,
but I think some of the tables are still very big.
