The thicknesses and inclinations of 71 northern spiral galaxies.

MA J., PENG Q.-H. and GU Q.-S.

Abstract (from CDS):

This paper presents the thicknesses and inclinations (i.e., the angle between the galactic plane and the tangent plane) of 71 northern spiral galaxies. The method for measuring the thickness has been proposed by Peng. It is based on the solution of Poisson's equation for a logarithmic disturbance of density. The inclination is determined by assuming that the pattern of spiral structure is a logarithmic spiral. We find that the thickness is correlated with color and with the Hα+[NII] equivalent width.
