Several statistical attempts were already made to discriminate between oblate forms vs. prolate forms (OF/PF) in elliptical galaxies (Marchant & Olson, 1979; Lake, 1979; Olson & de Vaucouleurs, 1981; Capaccioli et al., 1984). They fell in with the fundamental problem that the observed quantities (surface brightness, velocity dispersion, flattening etc.) whose projection should depend on the assumed shapes (OF/PF), could be intrinsically correlated each other. This can mask the simple projection–effect (Richstone, 1979; Merritt, 1982).
