Precision for different subsets of features for the tiles b234, b261, b278, and b360 for a fixed recall (∼0.9). From left to right: the first panel includes the total set of features; in the second, only the magnitude- and period-based features is used; in the third, the magnitude- and extinction-based ones; and, finally, the extinction- and period-based features are used. In all cases, the rows indicate which tile was used for train the RF classifier and the columns indicate the one used for the test.
