Catalog Service: UBV Astrometry and Photometry of doubles
Description
UBV CCD absolute photometry and differential astrometry of 111 southern visual binaries are presented. Observations have been performed at Las Campanas Observatory (Chile) in 1991-92 at 61-cm telescope. The separation range is 2.5-8arcsec. The mean epoch of the measurements is 1992.0. The photometry (table 1) was calibrated by one night of standard star observations. The positional parameters (table 3) are given in the reference system J2000 and calibrated using Hipparcos and CDS data. An additional table 2 provides the notes on observational circumstances.
