Value Added Catalogs

In addition to the primary SDSS photometry and spectroscopy, there are a few extra catalogs created by our collaborators that are distributed through the SAS. These Value-Added Catalogs (VACs) are listed below, and include catalogs that were released in earlier data releases.

Abstract

This Value Added Catalog contains properties for DA white dwarfs with optical spectra in SDSS. We include here measurements of radial velocity, spectroscopic and photometric effective temperatures, surface gravity, and radius, as described in Crumpler et al. (2025). The code used to derive the properties in this VAC is available on Github here. We are providing two files as part of this VAC:

eSDSS_DA_df.fits contains 19,257 unique DA white dwarfs identified by Gentile Fusillo et al. (2021) in SDSS Data Releases 1 through 16.
SDSSV_DA_df.fits contains 8,545 unique DA white dwarfs observed in SDSS Data Release 19
