Differences in position in the sense NIMA minus JPL ephemeris (same ephemeris version as that given in Table 5) for Centaur (10199) Chariklo. Left panel: differences in right ascension (black thick line) and declination (grey/blue thick line), where NIMA used observational data from the MPC and from the OPD. The thin grey lines show the 1-σ uncertainty of the differences. Right panel: differences in right ascension (black thick line) and declination (grey/blue thick line), where NIMA used observational data from the MPC and from the OPD and ESO.
