We have the ability to use either Gaia or PanSTARRS reference catalogs for astrometric fitting in jointcal.  As of DM-17597, the default was set to the Gaia reference catalogs (for astrometric fitting only, the default for photometry is still PanSTARRS PS1), but obs_subaru was still overriding to use PS1.  As of DM-25849, this override has been removed so that HSC processing now uses the jointcal defaults.  The scripts in pipe_analysis create plots and measure metrics based on a matching of pipeline sources to reference catalog sources and had PS1 hard-coded as the reference catalog that gets used in both types of calibration metrics.  Update the scripts to be able to use either Gaia or PS1 for astrometry.  PS1 is still the only contender for photometry (for both jointcal or fgcm bases photometric solutions).
