Description:
As part of an ongoing program on the main parameters of early-type
galaxies, we have performed long-slit absorption spectroscopy on a
sample of 21 ellipticals and S0s. We present determinations of the
central velocity dispersion and, for 18 objects, velocity-dispersion
profiles and rotation curves.

Note (1): PA (North --> East) is in the range [0, 360[, and with the
following 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.
Note (2): rotation and dispersion velocities are projected along the line
of sight; rotation values are with respect to the point r=0.

History:
The files table3.dat and table4.dat have been updated on 12 June 1997,
with1the following changes:
- object names are written without blank character,
- a convention on the PA angles has been introduced to coincide with that
adopted in the subsequent papers of the series. The galaxies for which PA
changes are: NGC 97, 1426, 1713, 2332, 2685, 2732, 2768, 3193, 3818, 4434,
4476, 4478, 7660, and 7727, and UGC 3696.
- minor format modifications have been made, again to conform to the formats
adopted in the subsequent papers.
Since the new convention on PA has incidence on the printed version of
Table 2, we are enclosing an additional file, table2.dat, which
presents the log of the observations with the new values, and which
may be useful to the readers.
