cds-question@unistra.frgalaxiesphotometrygalaxy-classification-systemsA variety of formation scenarios have been proposed to explain the diversity of properties observed in bulges. Studying their intrinsic shape can help to constrain the dominant mechanisms at the epochs of their assembly. The structural parameters of a magnitude-limited sample of 148 unbarred S0-Sb galaxies were derived in order to study the correlations between bulges and disks, as well as the probability distribution function of the intrinsic equatorial ellipticity of bulges. We present a new fitting algorithm (GASP2D) to perform two-dimensional photometric decomposition of the galaxy surface-brightness distribution. This was assumed to be the sum of the contribution of a bulge and disk component characterized by elliptical and concentric isophotes with constant (but possibly different) ellipticity and position angles. Bulge and disk parameters of the sample galaxies were derived from the J-band images, which were available in the Two Micron All Sky Survey. The probability distribution function of the equatorial ellipticity of the bulges was derived from the distribution of the observed ellipticities of bulges and misalignments between bulges and disks.2008A&A...478..353Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/478/353CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/478/353https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/478/353http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/478/353https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/478/353https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/478/353http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/478/353GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/478/353/table3 (Main properties and structural bulge and disk parameters of the galaxies in the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/478/353/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/478/353/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/478/353/table3?GETtext/xml+votable180.050000true195.2533333-32.44144440.0055555555555555566/43 144 177 664 2227 4149 4188 5181-5182 5429 5463 5572 5975 5982 6087 7214 7241 7385 7606 7658 7704 7957 7975 8196 10454 10511 10515 10531 10636 10638 10856 10878 10892 10925 11207 11246 11418 11435 11443 11738 12005 16464 17032 17274 17604 17671 18208-18209 18214 18285 18325 18458 18689 18692 18714 19227 19614 19900 20023 20031-20033 20060 20386 23306 24702 24775 24839 24913 25048 25052 25077 25238 26309 26346 26365 27426 27595 27712 27714 27720 27723 27730 27734 27738 27743 27764 27767 27918 27944-27946 28015 28033 28038-28039 28045 28149 28172 28221 28237 28264 28463 28524 28651 32482 32854 33802 33954 34326 34363 34377 34542 35316 35581 35923 35925 36045 36194 36247 36332 36662 36749 43875-43876 43915 43986 45118 45469 45491 45497 45828 45883 46017 46036 46158 46477 46689 46811 46987 47385 47397 47415 474671.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/478/353?format=asciiOpticaldefaultJ/A+A/478/353/table3Main properties and structural bulge and disk parameters of the galaxies in the samplerecnoRecord number assigned by the VizieR team.
