Investigate inaccuracy of initial HSC WCSs

    Details

      Description

      Gen3 ingest needs to be able to generate inclusive on-sky regions for all visits, using raw WCS and potentially camera geometry.  As those initial WCSs are inaccurate, we expect to need to pad somehow to ensure the region always includes the true region, even if it's much larger.

      As a result, we need to look at the difference between some initial HSC WCSs and their post-astrometry counterparts.

      This investigation could also be informative for future attempts to fit initial astrometry with as few free parameters as possible.
