2008ApJS..175...97H CGRaBS: An All-Sky Survey of {GAMMA}-Ray Blazar Candidates Healey, Stephen E.; Romani, Roger W.; Cotter, Garret; Michelson, Peter F.; Schlafly, Edward F.; Readhead, Anthony C. S.; Giommi, Paolo; Chaty, Sylvain; Grenier, Isabelle A.; Weintraub, Lawrence C. Abstract. We describe a uniform all-sky survey of bright blazars, selected primarily by their flat radio spectra, that is designed to provide a large catalog of likely gamma-ray active galactic nuclei (AGNs). The defined sample has 1625 targets with radio and X-ray properties similar to those of the EGRET blazars, spread uniformly across the |b|>10^deg^ sky. We also report progress toward optical characterization of the sample; of objects with known R<23, 85% have been classified and 81% have measured redshifts. One goal of this program is to focus attention on the most interesting (e.g., high-redshift, high-luminosity,...) sources for intensive multiwavelength study during the observations by the Large Area Telescope (LAT) on GLAST. Key words: Galaxies: BL Lacertae Objects: General, Galaxies: Active, Galaxies: Quasars: General, Surveys
