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.
The SDSS-IV Extended Baryon Oscillation Spectroscopic Survey: Emission Line Galaxy Target Catalog
Catalog of south galactic cap Emission Line Galaxies used for eBOSS target selection.
This value added catalog contains the south galactic cap Emission Line Galaxy (ELG) catalog used for eBOSS. Targets were selected using photometric data from the Dark Energy Camera Legacy Survey (DECaLS), and details of the selection techniques can be found in Raichoor et al. (submitted). We selected roughly 240 ELG targets per square degree, and the great majority of these ELG lie in the redshift range 0.67 < z < 1.1 (median redshift 0.85).
