Comparison of ESP-HS (top) and GSP-Phot (bottom) extinction estimates A₀ for hot stars in star clusters. We used the cluster members and mean extinctions from Cantat-Gaudin et al. (2020). We computed the GSP-Phot and ESP-HS median estimates using only stars with T_eff > 7500 K. We colour-coded the data by the number of hot star members with estimates we found in the cluster (with respect to the colour bar at the top). In both panels, the grey lines represent the identity relation, and the blue lines a linear regression through the data points. The insets show the normalised distribution of the differences, A₀(GSP-Phot or ESP-HS)–A₀(literature).
