zuds-pipeline's Issues

Allow user to specify list of seeing calibrators

Request from @nugent68.

In estimate_seeing (and the call to it from make_coadd) update the interface to allow the user to pass a custom catalog of seeing calibrators in astropy table readable format, or a PipelineFITSCatalog object.
