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 the outcomes of a Random Forest Classifier for classifying z<0.8 emission line galaxies into subtypes of star-forming galaxies, composites, AGNs and LINERs with accuracies of 93.7%, 68.3%, 70.5% and 64.4%, respectively. The classification code is available here, and more details of this catalog are described in Zhang et al. (2019).
