1987ApJ...313...42D Spectroscopy and photometry of elliptical galaxies. I - A new distance estimator Alan Dressler, Donald Lynden-Bell, David Burstein, Roger L. Davies, S. M. Faber, Roberto Terlevich, and Gary Wegner Abstract. Spectral and photometric data were gathered for 97 elliptical galaxies in six rich clusters as part of an all-sky survey of elliptical galaxies. The data are used to disprove a previously proposed correlation between the residuals from the mean Mg(2) line, velocity dispersion and line strength for elliptical galaxies. The correlation is shown to be an artifact of a distance error in the field sample. A photometric distance estimator is defined which is the diameter enclosing an integrated surface brightness of elliptical galaxies. The estimator is strongly correlated with the velocity dispersion, luminosity and the surface brightness within the effective radius. The new method is employed to calculate relative distances for the Virgo, Fornax and Coma clusters.
