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 catalog contains sources identified as spectroscopic binaries (SB2s) and higher order multiples in the DR17 APOGEE data, as well as radial velocities (RVs) of the individual components. The sources were identified through Gaussian deconvolution of the cross-correlation function of each system, using an autonomous pipeline available on GitHub here. The pipeline is described in more detail in Kounkel et al. 2019, and this catalog is presented in Kounkel et al. (2021).
