cds-question@unistra.frgalaxiescatalogsgalaxy-classification-systemsWe present two methods that can be used to deproject spirals, based on Fourier analysis of their images, and discuss their potential and restrictions. Our methods perform particularly well for galaxies more inclined than 50 degrees or for non-barred galaxies more inclined than 35 degrees. They are fast and straightforward to use, and thus ideal for large samples of galaxies. Moreover, they are very robust for low resolutions and thus are appropriate for samples of cosmological interest. The relevant software is available from us upon request. We use these methods to determine the values of the position and inclination angles for a sample of 81 spiral galaxies contained in the Frei et al. (1996AJ....111..174F) sample. We compare our results with the values found in the literature, based on other methods. We find statistically very good agreement.2004A&A...415..849Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/415/849CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/415/849https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/415/849http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/415/849https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/415/849https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/415/849http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/415/849GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/415/849/table7a (Deprojecting information for 81 galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/415/849/table7a?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/415/849/table7a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/415/849/table7a?GETtext/xml+votable180.050000true114.21087565.6026670.0055555555555555566/4149 4511 5067 5142 5202 5492 5545 5572 5581 5587 5596 5629 5715 5751 5966 6619 7424 7602 7606 7659 7743 7957 8042 8196 8320 8359 10475 10637 10817 10841 10941 10977 10991 11000 11389 11448 11566 11639 25438 25513 25599 25997 26090 26148 26303 26336 26472 27512 27514 27653 27728 27757 27828 27857 27861-27862 27914 27917-27918 27926 27937 27942 27945 27955 28015 28035 28037-28039 28045 28123 28173 28208 28496 28521 28529 30970 31880 45054https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/415/849?format=asciiOpticaldefaultJ/A+A/415/849/table7aDeprojecting information for 81 galaxiesrecnoRecord number assigned by the VizieR team.
