Distributions of the TP and FN classes for the RRL stars in all tiles according to the six most important features to differentiate them. In the top row, all the stars are compared, in the mid row, only the RRL-AB type, and in the low row, the RRL-C type. From right to left, the columns corresponds to: period_fit, Psi_eta, PeriodLS, ppmb, Psi_CS, and Freq1_harmonics_amplitude_0. All features were converted to z-scores and are dimensionless.
