Comparison between the log g values for stars with KMgiantPar = 0 as derived in GSP-Spec (calibrated based on the T_eff) and in the XGBoost catalog. Cyan and purple circles correspond to stars with GSP-Spec calibrated surface gravities smaller and larger than 2.2 dex, respectively. In the later, the XGBoost parameters were adopted. The activity index (available for a subsample of sources) is shown in the color bar. Stars having overestimated GSP-Spec surface gravities are precisely those sources with enhanced activity.
