Notes. Column 1: TNO ID; Col. 2: total number of WFI frames used to cover the sky path of the respective TNO from 2012.5 to the end of 2014; Col. 3: magnitude completeness; Col. 4: total number of entries for all three catalogues with positions and proper motions (WFI catalogues, see text); Cols. 5 and 6: standard deviation of the offsets (observed minus catalogue position) in right ascension and declination, respectively, for the UCAC4 stars; Cols. 7 to 9: per cent of stars whose proper motions came directly from the UCAC4 or from a combination between the observed (WFI) position and either 2MASS or USNO-B1; Col. 10: per cent of stars in the positions and proper motions catalogue that have f0 for quality astrometry. Flags range from 0 (f0: good astrometry) to 5 (f5: position derived from one measurement only). The lower the flag number, the more reliable the position (see Assafin et al. 2010, 2012 for further details); Cols. 11 to 13: number of predicted events per year. No selection was made in this counting so that, for instance, occultations occurring during daylight were also considered.

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.
