| Abstract: | A database for the entire catalog of the Second Byurakan Survey (SBS) galaxies is presented. It contains new measurements
of their optical parameters and additional information taken from the literature and other databases. The measurements were
made using Ipg (near-infrared), Fpg (red), and Jpg (blue) band images from photographic sky survey plates obtained by the Palomar Schmidt telescope and extracted from the STScI
Digital Sky Survey (DSS). The database provides accurate coordinates, morphological type, spectral and activity classes, apparent
magnitudes and diameters, axial ratios and position angles, as well as number counts of neighboring objects in a circle of
radius 50 kpc. The total number of individual SBS objects in the database is now 1676. The 188 Markarian galaxies that were
re-discovered by SBS are not included in this database. We also include redshifts that are now available for 1576 SBS objects,
as well as 2MASS infrared magnitudes for 1117 SBS galaxies. |
