Notes. Multiplicity flag statistics for each and all TNOs. Percentages refer to the total number of mosaic positions for each TNO and for all TNOs together (last line). No flag (good astrometry) means no multiple entries within 1
5 for the same object after mosaic solutions. Flag cases f1 and f2 apply only to UCAC2 and 2MASS stars, when only entries assigned to a catalog were used. Flag f1 means that more than one entry was used (more than one position entry was averaged), whereas flag f2 indicates that only one entry was used. Flags f3, f4, and f5 apply only to field stars and mean that only one entry was selected according to one of three criteria, in order of priority: a) highest number of used common individual CCD positions (flag f3); b) least (x,y) measurement error (flag f4); c) brightest R magnitude (flag f5).
