Comparison of XLFs of different populations.

Lmin = 1035 Lmin = 1036

P(RF < RGC)  <10-7      (>5σ) 3.6 × 10-4      (3.6σ)
P(RC < RGC) 8.3 × 10-3      (2.6σ) 4.6 × 10-3      (2.8σ)

Notes. RGC, RF, and RC are ratios of the number of faint sources (Lmin < Lx < 1037 erg s-1) to the number of bright sources (Lx > 1037 erg s-1) for GCs, field sources, and sources in the inner 1′ of M 31. P is the probability that the luminosity distributions of corresponding populations are drawn from the same mean (see text for details).
