Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

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
    50kpc. The total number of individual SBS objects in the database is
    now 1676. The 188 Markarian galaxies which 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.

Description:
    Images extracted from the STScI Digitized Sky Survey (DSS) of Fpg(red)
    Jpg(blue), and Ipg(NIR) band photographic sky survey plates obtained
    by the Palomar telescope.

Note (1): As it appears in the original lists (Stepanian, 2005RMxAA..41..155S) Note (2): The numerical coding used here for the morphological description of the galaxies is a slightly modified and simplified version of the morphological types T given in the RC3 catalog. The codes used are as in the codes.date file Note (3): According to Stepanian, 2005RMxAA..41..155S. Note (4): Activity class, when available, or description of the spectra according to (Stepanian, 2005RMxAA..41..155S) and DR7 of SDSS. The various Seyfert classes are denoted by 'Sy1', 'Sy1.5', 'Sy1.8', 'Sy1.9' and 'Sy2'. The symbol 'Sy3' refers to LINERs. Starburst and HII nuclei respectively are indicated by 'SB' and 'HII'. QSOs and BL Lacertae objects are also identified. Note (5): Measured from North (PA=0 degrees) toward East between 0 and 180deg. For round galaxies with axial ratio R(J)~1.00 position angles were not measured. Note (6): 'nd' indicates a Markarian galaxy with redshift smaller than 0.005 and no neighbor counts were performed. Note (7): For 1117 galaxies 2MASX (e.g. Jarrett et al. 2000AJ....119.2498J) total J, H and K magnitudes are listed.
