That uvrange should leave PT out entirely I would have thought.  3C286
is just too extended for such baselines.  The curiosity is why the
other data set worked - perhaps other calibration sources?

We are working on models for 3C286 and the other 3 main flux cals but
have not yet reached L band.  These models come with aips and use verb
CALDIR to tell you which are currently available.  With the models one
can calibrate much better than with uvrange.
