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.

Granada FSPS Stellar Masses

Scientific Analysis Catalog

Galaxy stellar masses based on Flexible Stellar Population Synthesis by the Granada group, for BOSS galaxies.

Catalog Data

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


Granada Flexible Stellar Population Synthesis (FSPS, Conroy et al. 2009) stellar masses (Montero-Dorta et al. 2016) are calculated using the BOSS spectroscopic redshift, Z_NOQSO and u,g,r,i,z photometry by means of broad-band spectral energy distribution (SED) fitting of models based on a grid of templates. The flexibility of the model templates allows for a variety of formation-time scenarios including early formation-time (with and without dust), and a wide range of formation times. Calculations have been carried out for both Salpeter (1955) and Kroupa (2001) initial mass functions.
