Major axis kinematics of 15 early-type galaxies in the Fornax cluster

Abstract

Major axis rotation curves and velocity dispersions profiles, extending out to about one effective radius, are presented for 15 ellipticals and S0's out of the photometric sample of Fornax cluster galaxies studied by Caon \etal\ (1994). A brief description of the spectroscopic and photometric characteristics of each galaxy is provided, together with a comparison with previous studies. Six of the nine E's are possibly misclassified S0's or ellipticals harboring a disk-like component. Two galaxies (NGC~1399 and 1404) show a hint of counter-rotation. Evidence is given that the \bright\ and the \ordinary\ families of early-type galaxies, first introduced by Capaccioli \etal\ (1992), look distinct also in term of the anisotropy parameter $(\Vm/σ)^*$.
