Determinations of the heliocentric radial velocity
, of
, and of
(together with the
corresponding radius
) are listed in the last columns of
Table 1. The V(r) and
profiles are presented in
Fig. 1, and also in Table 3, which
is proposed in electronic form only. As in Paper III, we have adopted
the following convention for the position angle PA: for
, r<0 corresponds to the eastern side of the galaxy,
for
, r<0 corresponds to the western side, and for
, r<0 is to the North. Tables 1 through 3 are available
from the CDS.

Figure 1:
Profiles of rotation velocities and velocity dispersions |
Our results are summarized as follows:
- We have measured the central velocity dispersion
for 25
galaxies: 20 Es, four S0s, and a spiral.
- For 15 galaxies in our sample, we have been able to determine the
and V(r) profiles along the major axis and, for another one,
along an intermediate axis. Whenever possible (for 16
galaxies), we have determined the maximum rotation velocity
:
this parameter was still unavailable for six of these objects.
The data presented here, together whith those of the
preceding papers of the
series, are available in the
HYPERCAT on-line catalog browser
(Prugniel et al. 1998), at
