Deprojection of spiral galaxies
Listed in IVOA Registry (Virtual Observatory)
We present two methods that can be used to deproject spirals, based on Fourier analysis of their images, and discuss their potential and restrictions.
Description
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.
