Abstract:
We present extended stellar kinematics for a sample of elliptical
galaxies in the Fornax cluster. Out of the 13 galaxies presented here,
five (FCC 119, FCC 136, NGC 1373, NGC 1428, FCC 335) have no
previously published kinematical data. Major-axis velocity dispersion
profiles (VDPs) and rotation curves (RCs) are given for 12 of the
galaxies. A major feature of this data is the spatial extension: for 8
galaxies the data extends beyond 1R_e_, and for 5 it extends beyond
2R_e_. Compared to the previously available data, this corresponds to
an increase in spatial coverage by a factor from 1 to 5. The present
sample represents 86% of the ellipticals in Fornax brighter than
B_T_=15mag.
