[daip] zero vis

Hi all,

Because I'm running the (VLBA) pipeline, I am concerned about robustness.  
At least one task -CLIPM- can be improved in my opinion.

CLIPM, and maybe other tasks, cycles through the source list to do its job
(fitting a continuum to the source and clip on the residuals). However,
some observations end up with zero visibilities in the data, eg due to long
slews. To me, zero visibilities should mean that there is nothing to clip -
not croak. The only way to get CLIPM to finish now is to physically remove
that source from the SU list. Could you perhaps put a statement in CLIPM to
skip the source if there are no visibilities for a particular source?
Thanks anyway.


Regards,
