2. Sample and observations

Our present sample consists of 24 early-type galaxies, with nine ellipticals and 15 S0s. This set adds up to the 21-object and 38-object samples of Papers I and II; there are four objects in common with Paper I and two with Paper II: these additional measurements have been included in the present work for comparison purposes. Relevant catalog elements are presented in Table 1 (click here). The Es have ellipticities corresponding to classes between E1 and
E4, and the S0s are moderately to highly flattened. The distances are in the range of to Mpc (for ). These objects are intrinsically bright (-22.1< M_B < -18.9).

The observations have been secured at the 1.93-m telescope of the Observatoire de Haute-Provence, equipped with the CARELEC long-slit spectrograph. In November 1993, November and December 1994, three observing runs totalling 10 nights collected spectra on the major axis of the galaxies and, for five of them, on the minor axis as well.

The atmospheric conditions were variable, with a seeing disk between 2'' and 3.5'' (FWHM) for most objects, but up to for three of them. The log of the observations is given in Table 2, which is proposed in electronic form only.
