Notes. The 1%, 50% (median), and 99% percentile are provided for each type. (a) For RR Lyrae stars, the percentiles for GBP and GRP were computed for a number of FoV transits > 1, although there are stars with 0 or 1 transit remaining in the band after our cleaning. For the skewness and kurtosis, we included only RR Lyrae stars with > 2 and > 3 transits, respectively.
