Redshift distribution of ~5200 simulated Gaia quasars from Robin et al. (2012) brighter than GRVS = 17 mag in redshift bins of 0.2 (red). The fraction of these quasars that also have a broad emission line in the RVS (579 objects) are shown in black. Their smaller bin widths represent the redshift range when at least one BEL wing falls in the RVS pass band (see Table 2).
