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.

历史视觉双星测量的不确定性- iii精确校准对

基于天基位置和固有运动，给出了857对天球上双星对的精确直线元。这些元素允许计算精确的星历、位置、角度和这些对的距离。我们建议将这些对作为天体测量校准对纳入双星观测计划。

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
