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
Abstract
Wisconsin stellar masses and velocity dispersions are derived from the optical rest-frame spectral region (3700-5500 Ångstroms) using a principal component analysis (PCA) method (Chen et al. 2012). The estimation is based on a library of model spectra generated using the single stellar population models of Bruzal & Charlot (2003) and Maraston & Strömbäck (2011), and with a broad range of star-formation histories, metallicities, dust extinctions, and stellar velocity dispersions.
