Table name: AGK3 Records: 183128 Version: Spectral Band: OPT,PHOTO Kind of Object: Star Mode: Astrometry,Proper Motion Preview: no Coordinates: B1950
The overall precision of the coordinates is 0".021 (standard error, weighted mean). The standard error of the proper motions is of the order of 0".010/year. In the case of large discrepancies in position the star is omitted, and if the discrepancy showed up only in AGK2 the proper motion is omitted.
