Distribution of photon index Γ, pexrav reflection factor R, and Fe Kα line EW (from left to right) for our sample and radio-quiet sources in PW19. The green lines mark sources with only upper limits to R or EW in our sample. Apparently, all three parameters are smaller in our sample than in PW19. The difference is significant at 99.7% confidence for Γ (K-S test) and >99.9% confidence for both R and EW (using log-rank test within ASURV to handle the censored data points).
