Here are a few notes about astrometry/photometry reference catalogs:
- If you’re using the
sdss-dr9-fink-v5bastrometry.net catalog (SDSS DR9 with photometric corrections by Doug Finkbeiner), there is a paper you can reference: Hypercalibration: A Pan-STARRS1-based recalibration of the Sloan Digital Sky Survey. I’m not sure if v5b is the absolute-latest and best version of Doug’s recalibration, but I trust it’s close. I’m not sure it fixes those notorious 3 bad fields in Cosmos though… If you’re not using this, you can get it from
- Once we’re ready with the new reference catalog format, I hope to move the
sdss-dr9-fink-v5bcatalog into that format and make it generally available.
- I understand the Pan-STARRS1 team now have the PV3 3pi catalog calibrated, and are getting ready to stuff it in the database. I hope this means that the data will be public soon (for some value of “soon”…). Once it is, I hope to stuff it into the new format and release it for use.
