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.
