Table A.1
Number of visually inspected DR10 BOSS quasar targets (third column) and identifications in the DR10Q catalog for each target selection method (first column; see Table 4 of Ross et al. 2012, and Tables 6 and 7 in the appendix of Dawson et al. 2013). These categories overlap because many objects are selected by multiple algorithms.
