Abstract
Major axis rotation curves and velocity dispersions profiles, extendin g out to about one effective radius, are presented for 15 ellipticals and SO's out of the photometric sample of Fornax cluster galaxies stud ied by Caon et al. (1994). A brief description of the spectroscopic an d photometric characteristics of each galaxy is provided, together wit h a comparison with previous studies. Six of the nine E's are possibly misclassified SO's or ellipticals harboring a disk-like component, Tw o galaxies (NGC 1399 and 1404) show a hint of counter-rotation. Eviden ce is given that the bright and the ordinary families of early-type ga laxies, first introduced by Capaccioli et al. (1992), look distinct al so in term of the anisotropy parameter (V-m/sigma).
