Beginning of ReadMe : J/AN/338/61 The GSH Binary Survey (Mugrauer+, 2017) ================================================================================ The Grossschwabhausen Binary Survey. Mugrauer M., Buder S., Reum F., Birth A. <Astron. Nachrichten 338, 61-73 (2017)> =2017AN....338...61M (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Surveys ; Stars, double and multiple ; Positional data ; Photometry, CCD Keywords: binaries: visual - methods: observational 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.
