Notes. Parameters used in training. All parameters were derived from light curves with 500 s uniform time bins. First column is a designation of the parameter in the WP2 catalog. Second column is the description of the parameter. Third column is the ratio of standard deviation to median absolute deviation.
(a) Tail probabilities (p-values) were recalculated with higher precision and transformed into one-sided sigma values such that higher sigma corresponds to a poorer model fit.
