Boxplot of the signal detection efficiency for the general-purpose algorithms from Wōtan tested on the active sample with injected transit signals with R_p ~ 0.5 R_J and P_orb ∈ [1–15] days, moving on circular orbits. Boxes cover the lower to upper quartiles; whiskers show the 10 and 90 percentiles. Dashed black lines indicate the mean SDE, whereas red lines the median. The black circles in the biweight (1.0 day) and the lowess (1.0 day) cases represent data that extend beyond the whiskers.
