Abstract:
We present kinematical data for a sample of 26 galaxies. Rotation
curves and velocity-dispersion profiles are determined for all
objects. This is our fifth paper in a series devoted to the
presentation of data on elliptical and S0 galaxies, derived from
long-slit absorption spectroscopy; the series now gathers 119 galaxies
with homogeneous data.

convention on the subsequent radius r in the profiles (Table 3):
- for 0<PA<180, r<0 corresponds to the eastern side of the galaxy,
- for 180<PA<360, r<0 corresponds to the western side,
- and for PA=0, r<0 is to the North.

convention:
- for 0<PA<180, r<0 corresponds to the eastern side of the galaxy,
- for 180<PA<360, r<0 corresponds to the western side,
- and for PA=0, r<0 is to the North.
