Latitude profiles of source counts in the case of two-class classification. Solid blue lines represent associated 3FGL and 4FGL-DR2 sources; red dash-dotted lines show counts of all unassociated sources; blue bands show the envelope of sums of class probabilities for associated sources for the eight ML methods with and without oversampling corrected for the presence of OTHER sources; green bands show the envelope of sums of class probabilities for unassociated sources for the eight ML methods corrected for the presence of OTHER sources; solid orange lines (bands) show the average (envelope) of sums of class probabilities for the eight ML methods added to the source count of associated sources; green dotted lines on the AGN plots show the mean of the orange solid lines; and gray dashed (dotted) lines show the RF (LR) sums of class probabilities from Saz Parkinson et al. (2016) (for details, see Sect. 6.2).
