I was trying to reduce some Palomar mosaic data within mscred,
using an instrument description file in a private mscdb kindly
provided by a previous user. Anyway - I must be missing something
in calling the mscred version of zerocombine, because it
consistently gives a string of "Warning: FXF: must specify which
FIST extension..." messages. I even explicitly called
mscred.zerocombine to make sure it wasn't trying to call the
ordinary one from ccdred.Hints appreciated...Thanks,Bill Keel
