J/AJ/140/1987       SDSS-GALEX QSO catalog                   (Hutchings+, 2010)

A catalog of 19,100 quasi-stellar object candidates with redshift 0.5-1.5. Hutchings J.B., Bianchi L. <Astron. J., 140, 1987-1994 (2010)> =2010AJ....140.1987H
ADC_Keywords: QSOs ; Photometry, ultraviolet ; Photometry, SDSS Keywords: quasars: general Abstract: We discuss a sample of ∼60000 objects from the combined Sloan Digital Sky Survey-Galaxy Evolution Explorer (SDSS-GALEX) database with UV-optical colors that should isolate QSOs in the redshift range 0.5-1.5. We use SDSS spectra of a subsample of ∼4500 to remove stellar and galaxy contaminants in the sample to a very high level, based on the 7-band photometry. We discuss the distributions of redshift, luminosity, and reddening of the 19100 QSOs (∼96%) that we estimate to be present in the final sample of 19812 point sources. File Summary:
