Abstract:
A database for the entire Markarian catalog is presented that combines
extensive new measurements of their optical parameters with a
literature and database search. The measurements were made using
images extracted from the STScI Digitized Sky Survey (DSS) of
Fpg(red) and Jpg(blue) band photographic sky survey plates
obtained by the Palomar and UK Schmidt telescopes. We provide accurate
coordinates, morphological type, spectral and activity classes, red
and blue apparent magnitudes, apparent diameters, axial ratios, and
position angles, as well as number counts of neighboring objects in a
circle of radius 50kpc. Special attention was paid to the individual
descriptions of the galaxies in the original Markarian lists, which
clarified many cases of misidentifications of the objects,
particularly among interacting systems, larger galaxies with knots
of star formation, possible stars, and cases of stars projected on
galaxies. The total number of individual Markarian objects in the
database is now 1544.

Images extracted from the STScI Digitized Sky Survey (DSS) of Fpg(red)
and Jpg(blue) band photographic sky survey plates obtained by the

--------------------------------------------------------------------------------
Note (1): As it appears in the original lists. For objects newly added to
the database, we add an 'a' or 'b' letter designation (e.g. Mrk799a
and 799b). In all cases, the eastern galaxy or component is labeled
'a', and the western galaxy or component with 'b'. There are three
duplications in the lists. Mrk107 is the same object as Mrk20, Mrk1318
is Mrk49, and Mrk890 is Mrk503.
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:
----------------------------------------------------------------------
-5 = E 1 = Sa 6 = Scd 10 = Im 14 = Compact
-3 = E/S0 2 = Sab 7 = Sd 11 = Im/BCD 15 = Interacting/Merger
-2 = S0 3 = Sb 8 = Sdm 12 = BCD/Im 16 = HII region
0 = S0/a 4 = Sbc 9 = Sm 13 = BCD
5 = Sc
----------------------------------------------------------------------
The additional morphological remarks include a 'B' for the presence of
a bar.
Note (3): According to the Markarian et al., 1989 (Cat. VII/172) catalog.
For newly added Markarian objects spectral classes are from
descriptions of these objects in the original lists.
Note (4): The various Seyfert classes are denoted by the symbols 'Sy1',
'Sy1.5', 'Sy1.8', 'Sy1.9', and 'Sy2'. The symbol 'Sy3' refers to
LINERs. Starburst nuclei are indicated by 'SB' and galaxies with
Wolf-Rayet features in their spectra are indicated with the symbol
'WR'. QSOs, BL Lacertae objects, Galactic stars (isolated or projected
on the galaxies) are also identified. New determinations and revised
AGN classes are included and described in the corresponding notes to
the database.
Note (5): At the position of Markarian object from HYPERLEDA and calculated
according to Schlegel et al. (1998ApJ...500..525S 1998ApJ...500..525S) maps.
Note (6): Measured from North (PA=0 degrees) toward East between 0 and 180
degrees. For round galaxies with axial ratio = 1.00 position angles
were not measured.
Note (7): 'd' indicates a Markarian galaxy with redshift smaller than 0.005
and no neighbor counts were performed
Note (8): For 1372 galaxies 2MASX (e.g. Jarrett et al. 2000AJ....119.2498J 2000AJ....119.2498J)
total J, H and K magnitudes are listed. For 12 Markarian galaxies,
2MASS observations are absent and for these galaxies J or J and K
magnitudes are from DENIS observations (Paturel et al., 2005, Cat.
VII/242). These 12 galaxies are: Mrk616, 902, 964, 981, 1059, 1154,
1188, 1256, 1309, 1382, 1394 and 1504.
