Notes. The 1%, 50% (median), and 99% percentile are provided for each type. (a) Cepheid groups: best_class_name = CEP, ACEP, T2CEP. (b)RR Lyrae star groups: best_class_name = RRAB, RRC, RRD, ARRD. (c) Long-period var. is best_class_name = MIRA_SR. (d) δ Sct and SX Phe is: best_class_name = DSCT_SXPHE. (e) For the skewness and kurtosis, we included only stars with >2 and > 3 FoV transits, respectively.
