Dispersion of Pluto’s ephemeris offsets before (top) and after the differential chromatic refraction (middle) and Pluto photocenter corrections (bottom). Histograms of right ascension are on the left and of declination are on the right. Ephemeris positions refer to the DE421+plu021 ephemerides from JPL. We note, as explained in the two previous sections, that the middle and bottom panels do not need to be revisited under a change of ephemeris, given that our corrections are not dependent on ephemerides positions.
