Markarian galaxies. I. The optical database and atlas. Petrosian A., McLean B., Allen R.J., MacKenty J.W. <Astrophys. J. Suppl. Ser., 170, 33-70 (2007)> =2007ApJS..170...33P
ADC_Keywords: Galaxies, Markarian ; Galaxy catalogs ; Photometry, infrared ; Magnitudes, photographic Keywords: astronomical data bases: miscellaneous - atlases - galaxies: active - galaxies: interactions - galaxies: starburst 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. Description: 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. File Summary:

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) 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) 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. Note (9): References explained in refs.dat file.
