Beginning of ReadMe : VII/143 Quasar Candidates (Crampton+ 1985-1990) ================================================================================ Quasar Candidates from grens plates Crampton D., Schade D., Cowley A.P.: 1985 <Astron. J. 90, 987 (1985)> =1985AJ.....90..987C Quasar candidates in two extended CFHT fields: 1338+27 and 1639+40. Crampton D., Cowley A.P., Schmidtke P.C.: 1988 <Astron. J. 96, 816 (1988)> =1988AJ.....96..816C Redshifts of quasars in the CFHT/MMT survey. III. Crampton D., Cowley A.P., Hartwick F.D.A: 1990 <Astron. J. 100, 47 (1990)> =1990AJ....100...47C ================================================================================ ADC_Keywords: QSOs ; Redshifts Description: This data set is based on data in three publications. The positions and magnitudes of quasar candidates discovered on Canada-France Hawaii-Telescope (CFHT) blue green plates are given. Spectroscopy with the Multiple Mirror Telescope (MMT) indicates that 70 percent of the candidates are quasars, and most of the others are white dwarfs or hot subluminous stars. Most of the redshifts are less than z=1.7. Additional spectroscopic observations at Steward Observatory were used. The catalog lists a name based on position, B1950 position, B magnitude, or visual magnitude, redshift, and remarks.
