Caption: Fig. 2.

Left: Histogram of separations for FBQS candidates identified as quasars (Q), BL Lac objects (B), narrow‐line AGNs (A), H II/star‐forming galaxies (H), galaxies without emission lines (G), and stars (S). Right: Fraction of quasar identifications as a function of separation. The error bars give the uncertainty in the mean fraction based on the binomial probability distribution. Quasars are strongly concentrated toward small separations.
