Catalog of X-ray & WISE AGN in the SDSS-IV eBOSS Stripe 82X Survey

This catalog contains 4847 spectroscopically identified X-ray sources and WISE AGN candidates within the 36.8 deg² SDSS-IV eBOSS Stripe 82X survey area. This survey overlaps the largest contiguous portion of the Stripe 82 X-ray survey (15.6 deg²). Based on X-ray luminosities or WISE W1-W2 colors (based on Assef et al. 2018), there are 4730 AGN in this catalog: 1790 X-ray AGN and 3638 WISE AGN, of which 698 are X-ray and WISE AGN. The sample is 82% complete to r ~ 22, where the X-ray and WISE AGN samples are 88% and 82% complete, respectively, at this magnitude limit.

The redshifts and spectroscopic classifications include spectra from the SDSS-IV eBOSS Stripe 82X survey, previous data releases of SDSS (Abazajian et al. 2009; Aihara et al. 201; Alam et al. 2015; Albareti et al. 2017; Abolfathi et al. 2019; Pâris et al. 2017, 2018), 2SLAQ (Croom et al. 2009), 6dF (Jones et al. 2004, 2009), and dedicated follow-up programs of Stripe 82 X-ray sources (LaMassa et al. 2016, 2017, and published here for the first time). Description of the catalog columns are given in LaMassa et al. (2019).
