cds-question@unistra.frgalaxiesphotometrygalaxy-classification-systemsWe present a nonparametric method for decomposition of the light of disk galaxies into disk, bulge, and bar components. We have developed and tested the method on a sample of 68 disk galaxies for which we have acquired I-band photometry. The separation of disk and bar light relies on the single assumption that the bar is a straight feature with a different ellipticity and position angle from that of the projected disk. Here we present the basic method, but we recognize that it can be significantly refined.2007AJ....133.2846Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/2846CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/2846https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/2846http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/2846https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/2846https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/2846http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/2846GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/133/2846/table1 (Galaxy Photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/2846/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/2846/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/2846/table1?GETtext/xml+votable180.050000true161.127975-14.31449720.0055555555555555565/6262 6/24957 24958 25035 25041 25042 25043 25044 25046 25061 25065 25279 25295 25300 25305 25306 25308 25315 25316 25318 25320 25322 25362 25368 25369 25380 25385 25613 25620 25624 25634 25635 25637 25638 25640 25641 26642 26646 26661 44756 44757 44771 44774 44815 44822 44824 44826 44835 44844https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/133/2846?format=asciiOpticaldefaultJ/AJ/133/2846/table1Galaxy PhotometryrecnoRecord number assigned by the VizieR team.
