Uncertainties in Historic Visual Double Star Measures— <scp>III</scp> Accurate Calibration Pairs
ABSTRACT Based on space‐based positions and proper motions, we present accurate rectilinear elements for 857 double star pairs over the celestial sphere. These elements allow for the computation of precision ephemeris Position Angles and Separations of these pairs. We propose these pairs as astrometric calibration pairs for inclusion in double‐star observation programmes.
