Data model: astromQAFieldSummary

General description: This file lists astrometric QA summary information for each field in a given RUN and CAMCOL, in comparison with a reference catalog. It contains the median position and (where appropriate) proper motion offsets.

Naming convention: astromQAFieldSummary-CAT-RUN-CAMCOL.fits.gz

Required column names:

• RUN (int32): SDSS run number
• CAMCOL (int32): camcol in SDSS run
• FIELD (int32): field in SDSS run
• DRA (float32): median right ascension offset from reference (SDSS minus reference), in arcsec
• DDEC (float32): median declination offset from reference (SDSS minus reference), in arcsec
• DPMRA (float32): median right ascension proper motion offset from reference (SDSS minus reference), in arcsec; exactly zero if no proper motion comparison made
• DPMDEC (float32): median declination proper motion offset from reference (SDSS minus reference), in arcsec; exactly zero if no proper motion comparison made
• CHECKED (int16): set if astrometric offsets were able to be checked with respect to this reference catalog for this field
• PMCHECKED (int16): set if proper motion offsets were able to be checked with respect to this reference catalog for this field
• CAT (string): reference catalog name
