Figure 4: Left: photometric vs. spectroscopic QSO redshifts: excluding outliers the rms is 0.007 and the bias is consistent with zero. Crosses are objects with two ambiguous photo-z solutions and are responsible for most outliers Right: type-1 AGN, encircled are those classed as QSO by COMBO-17: all but three QSOs with MB<-22 and z>0.5 are found, while fainter AGN are dominated by the host galaxy SED. |
