Comparison between Kepler magnitudes from the EPIC (Kp_EPIC) and the proxy magnitude for LC targets. The left part of each panel shows, for different campaigns, the difference in magnitudes against Kp_EPIC, and colour-coded by the bandpass colours used to compute Kp_EPIC. The right parts of the panels show KDEs for the differences from each bandpass colour, normalised to the number of targets with that input bandpass colour, and plotted in logarithmic units. Differences have been truncated to the interval between ± 5 (dotted lines). Note that in C0 the Kp_EPIC is given by the input colour from the principal investigator of the target, and the information on which colour is used is generally unavailable (N/A) in the EPIC.
