Color-Redshift Relations and Photometric Redshift Estimations of Quasars in Large Sky Surveys
Color-Redshift Relations and Photometric Redshift Estimations of Quasars in Large Sky Surveys
With a recently constructed composite quasar spectrum and the χ 2 minimization technique, we demonstrated a general method to estimate the photometric redshifts of a large sample of quasars by deriving the theoretical colorredshift relations and comparing the theoretical colors with the observed ones.We estimated the photometric redshifts from the …
