Astrometric Properties of the Schmidt Telescope of the Beijing Astronomical Observatory,

Abstract

The astrometric properties of the 60/90/180 em Schmidt telescope of the Beijing Astronomical Observatory have been investigated. One plate of the Pleiades cluster and another of the a Per moving cluster were measured by the Zeiss ASCORECORD measuring machine. The standard errors of measurement were +/-1.4 mu or +/-0."15in x and +1.5 mu or +/-0."17 in y. The standard deviation of the computed values using 10 plate constants in the entire field of 4.08 diameter from the eatalogu positions was +/-0."38 and in the field of 3.02 diameter was +/-0."34 (averaged for right ascension and declination). No visible magnitude dependence was found.
