Pluto’s ephemeris offsets between 2005 and 2013, in the sense observed minus ephemeris (DE421+plu021), obtained from the OPD (black dots) and ESO (blue circles) observations. The 16 ephemeris offsets from the stellar occultations (red dots) are also shown. Right ascension is on top and declination is on the bottom. All offset sets are in agreement, particularly in declination.
