Histogram of K2 data by magnitude. Note that there is no clear separation between “on-eclipse” and “off-eclipse” parts, except in very deep eclipses (relative flux <0.75, green line). The red dotted line marks the separation from the σ-clipping filter. Selecting down to a different level (e.g., 0.983, orange line, where the distribution appears to slightly flatten out) does not introduce any significant change.
