Top panel: comparison between our fit Γ (black circles) and the values obtained by Sridhar et al. (2020) for the five observations in common (squares, colour coded by the reflection strength as defined by Sridhar et al. 2020). The grey points with red contours refer to our whole sample. Bottom panel: similar comparison in the L_disc − L_cor plane where we highlight the difference between our original F_{cor,  3 − 25 keV} (black circles) and the reflection-corrected obtained with the reflection strength estimates computed by Sridhar et al. (2020).
