We show that the distribution of bulge Sersic indices, n_b_, is bimodal, and this bimodality correlates with the morphology of the bulge. Pseudobulges have n_b_~<2 and classical bulges have n_b_>~2 with little to no overlap. Also, pseudobulges do not follow the correlations of Sersic index with structural parameters or the photometric projections of the fundamental plane in the same way that classical bulges and elliptical galaxies do. We find that pseudobulges are systematically flatter than classical bulges and thus more disk-like in both their morphology and shape.2008AJ....136..773Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/136/773CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/182/216 : Surface photometry of Virgo ellipticals (Kormendy+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/136/773https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/136/773http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/136/773https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/136/773https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/136/773http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/136/773GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/136/773/table2 (Sample galaxy properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/136/773/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/136/773/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/136/773/table2?GETtext/xml+votable180.050000true23.5759792-29.41848890.0055555555555555566/4149 4447 4511 5181 5182 5631 5751 5982 6093 7241 7287 7485 7560 7606 7941 8458 10454 10841 10856 10977 11027 11460 12619 13401 13489 15592 18398 19611 24735 25599 25790 26271 26309 26362 26365 26803 27030 27255 27426 27458 27512 27514 27603 27714 27738 27743 27766 27871 27907 27914 27918 27937 27945 28015 28033 28037 28038 28045 28123 28167 28172 28495 28498 28516 28517 28538 28612 33193 33958 34404 35691 35925 36107 36236 36242 36261 36796 40328 45748https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/136/773?format=asciiOpticaldefaultJ/AJ/136/773/table2Sample galaxy propertiesrecnoRecord number assigned by the VizieR team.
