Abstract:
We present new kinematical data for a sample of 38 early-type
galaxies. Rotation curves and velocity-dispersion profiles are
determined for 32 objects, while the central velocity dispersions are
given for the whole sample. This is our second paper in a series
devoted to the presentation of kinematical data on elliptical and S0
galaxies, derived from long-slit absorption spectroscopy.

Note on Vrot and sigma:
Rotation and dispersion velocities are projected along the line of sight;
rotation values are with respect to the point r=0.
Note on PA and r:
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.
--------------------------------------------------------------------------------
History:
With respect to the printed version of the graphs, a change can be
noticed in the PA angles of a few galaxies (table4): this is due
to a new convention which is applied, starting with the printed
version of Paper III (in press), and which is aimed at suppressing an
uncertainty of 180 degrees on these angles. The convention is
explained, below, as notes to the files table2 and table4.
The changes are for the following galaxies: NGC 1521, 2332, 3921,
4435, 4464, 4479, and 4874, and UGC 3792.
