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.

Catalog Data

This dataset appears in DR12 SkyServer and CasJobs in the following tables:


Portsmouth spectral energy distribution (SED) fit stellar masses (Maraston et al. 2013) are calculated using the BOSS spectroscopic redshift, Z_NOQSO and u,g,r,i,z photometry by means of broad-band SED fitting of stellar population models. Separate calculations are carried out with a passive template and a star-forming template, and in each case for both Salpeter (1955) and Kroupa (2001) initial mass functions, and for stellar evolution with and without stellar mass loss.
