Deprojecting spiral galaxies using Fourier analysis. Application to the Ohio sample

Abstract

We use two new methods developed recently (Barberà et al. 2004, A&A, 415, 849), as well as information obtained from the literature, to calculate the orientation parameters of the spiral galaxies in the Ohio State University Bright Galaxy Survey. We compare the results of these methods with data from the literature, and find in general good agreement. We provide a homogeneous set of mean orientation parameters which can be used to approximately deproject the disks of the galaxies and facilitate a number of statistical studies of galaxy properties.
