Abstract:
    Optical positions of 2978 objects listed in the Second Byurakan Survey
    (SBS) were obtained using the Digitized Sky Survey (DSS), and are
    given with an rms un certainty ~1 arcsec in each coordinate.

Note (1): Optical magnitude for galaxies and photographic magnitude for 
    stellar objects. If the precision is specified in multiples of 0.01
    mag, the listed value is a photometric measurement with an accuracy
    <0.05 magnitude; otherwise the value represents an eye estimation of
    the photographic magnitude with an uncertainty of 0.5.
