2010AJ....140.1987H A Catalog of 19,100 Quasi-stellar Object Candidates with Redshift 0.5-1.5 Hutchings, J. B.; Bianchi, L. Abstract. We discuss a sample of ~60,000 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 19,100 QSOs (~96%) that we estimate to be present in the final sample of 19,812 point sources. The catalog is available as an online table. Key words: quasars: general
