Vϕ distribution of PGS. Counts with associated error bars (Poisson noise) are displayed in blue while PGS-APOGEE spectroscopic contaminants are displayed in purple. Contaminants are scaled by a factor equal to the size of PGS in each [Fe/H]PGS interval, divided by the size of APOGEE in the same intervals. Top panel: –1.0 < [Fe/H]PGS < –0.3. Middle panel: –1.7 < [Fe/H]PGS < –1.0. Bottom panel: –4.0 < [Fe/H]PGS < –1.7.
