Notes. Column 1: TNO ID; Cols. 2 and 3: offsets in the sense observed minus ephemeris positions for the respective TNO. These values result from a global reduction procedure; Cols. 4 and 5: internal precision of the offsets; Col. 6: Julian date; Col. 7: number of used references (UCAC4) stars; Col. 8: number of measurements used to estimate the figures in Cols. 2 to 5; Col. 9: TNO respective ephemeris version. All the ephemerides were taken from the HORIZONS JPL telnet service and were read with NASA’s SPICE tools.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
