Beginning of ReadMe : J/other/PASA/24.118 Wide southern double stars (Bauer+, 2007) ================================================================================ Astrometric observations of wide southern double stars - II. Bauer C., White G.L., Blank D., Jones P.A. <Publ. Astron. Soc. Australia, 24, 118-137 (2007)> =2007PASA...24..118B ================================================================================ ADC_Keywords: Stars, double and multiple ; Photometry, Cousins Keywords: Stars: double, multiple, binary Abstract: Astrometric CCD observations have been made of wide ( 3 to 60 arcsec) southern double stars selected from the Washington Double Star catalogue (WDS). Southern double stars have not been well studied in the past; typically they had not been measured since about 1930, and  50% of them have been observed only once before our observations. Of the pairs measured  80% show no evidence of motion since the last observation. This is Paper II in which we present the observations of 290 WDS stars in the approximate RA range 17h13m to 07h30m and in the declination range -70deg to -60deg. We suggest 412 companions for these 290 stars and list 29 (10%) pairs that have shown significant motion. Description: Observations were made during three periods, 6-10 October 1992, 4-25 November 1992 and 8-12 December 1993, with the last session being primarily concerned with calibration. The mean epoch of the observations is 1992.9. We used an SBIG ST6 CCD camera mounted on the f/18 focus of the 24 inch (0.6m) telescope of Mount Stromlo and Siding Spring Observatory (MSSSO) at Siding Spring Observatory (SSO), Australia. Images were obtained of each star through uncalibrated Cousins R and I filters. The stars were sufficiently bright that exposure times could be kept short, typically 180s or less.
