Notes. Selection flags given in the SDSS database: (a)Known QSO at z > 2.15; (b)Additional object observed to reach 40 QSOs deg−1 for BOSS outside the standard selection criteria; (c)Red optical to near/mid-infrared selection, classified as star in SDSS/BOSS; (d)Classified as a star in the SEGUE-2 survey; (e)FIRST radio selected; (f)Bright ugri-selected quasar; (g)Identified by the neural network and the kernel density estimation (KDE) plus χ2 algorithms of BOSS; (h)High-redshift griz-selected quasar; (i)Identified by the BOSS likelihood method; (j)Selected to be in the uniform BOSS core sample; (k)Filler target; (l)Classified as a blue horizontal branch star as part of the SEGUE target selection. (⋆)Quasars selected from the photometric selection criteria and identification algorithms defined specifically for the SDSS/BOSS surveys. (*)Metallicities from Kaplan et al. (2010) are either based on Si II, Zn II or S II, but the exact ion is not listed in their table 2, and for KV-RQ 1500–0013 the metallicity is derived from an empirical relation based on the equivalent width of Si II λ 1526.
