cds-question@unistra.frgalaxiesvisible-astronomygalaxy-classification-systemsBased on Peng's method (1988A&A...206...18P), we obtain scaleheights of 486 southern spiral galaxies, the images of which are taken from the Digitized Sky Survey at Xinglong Station of Beijing Astronomical Observatory. The fitted spiral arms of 70 galaxies are compared with their images to get their optimum inclinations. The scaleheights of other 416 ones are listed in Table 1 in Appendix. After compiling and analyzing the data, we find some statistical correlations. The most interesting results are that a flatter galaxy is bluer and looks brighter, and galaxies become flatter along the Hubble sequence Sab-Scd.1997A&AS..126..503Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/126/503CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/126/503https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/126/503http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/126/503https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/126/503https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/126/503http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/126/503GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/126/503/tablea1*The Measuring and Fitting ResultsNGC*NGC namemeta.idcharPGCPGC namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
