Abstract:
Since 2009 the Grossschwabhausen binary survey is carried out at the
University Observatory Jena. This new imaging survey uses available
time slots during photometric monitoring campaigns, caused by
non-photometric weather conditions, which often exhibit a good
atmospheric seeing. The goal of the project is to obtain current
relative astrometric measurements of binary systems, that are listed
in the Washington Visual Double Star Catalog. In this paper we
characterize the target sample of the survey, describe the imaging
observations, the astrometric measurements including the astrometric
calibration, and present relative astrometric measures of all
binaries, which could be obtained in the course of the survey, so far.
Description:
Relative astrometric measures for more than 350 binary systems from
the Washington Visual Double Star Catalog are presented. For each
system the angular separations and position angles of their secondary
components relative to the primary stars, as well as the magnitude
differences between both components, are given.
