J/MNRAS/403/1625  Method for orientation angles of galaxies  (Fridman+, 2010)

Using an assumption about the monotony of spiral arms to determine the orientation angles of galaxies. Fridman A.M., Poltorak S.G. <Mon. Not. R. Astron. Soc., 403, 1625-1632 (2010)> =2010MNRAS.403.1625F
ADC_Keywords: Models ; Galaxy catalogs ; Positional data Keywords: galaxies: spiral Abstract: A method is proposed for the determination of the position and inclination angles of the plane of a spiral galaxy based on the assumption that every spiral arm is a monotonic function of the radius against azimuthal angle. This method may yield more accurate results than the more commonly employed isophote method, which is subject to a number of drawbacks. Analytical study, calibration against other methods and examples of application of the proposed method to real galaxies are presented. File Summary:
