NGC 4379 .L..-P*-Exhibits a very smooth and featureless, classical central
morphology in HST F555W. The bulge radius is 8.6". The inset of the flattening
of the rotational velocity occurs already at 8-10". The velocity dispersion
profile is centrally peaked, rising from ~=90 km s^-1^ at 10" to ~=120 km s^-1^
in the center. The h_3_ moments are generally small (within the errors mostly
compatible with zero) but an overall trend points to anti-correlation with
velocity. The h_4_ values are noisy but mostly compatible with zero.
VCC 784 (NGC 4379).The isophotes become slightly disky at a distance of
approximately 10" from the center, as shown by the B4 coefficient and
ellipticity change between 10" and 20". Unlike the case of VCC 1883 and VCC 355,
there is no convincing evidence that a bar might be present, although the fact
that the position angle changes (just as it does for VCC 1883 and VCC 355 where
the bar sets in) is suggestive. The images and surface brightness profile are
clearly affected by the presence of a nucleus in the inner 0.2".

The apparent two-zone character of the
image is well shown in the negative print of NGC
4379 here. Comparison with images of any of the
galaxies in the E section shows the evident deviation
of the luminosity profile, characteristic of
the S0 types.
NGC 4379: This S0 contains an elongated disky feature tilted by some
10^deg^ relative to the inner bulge and outer disk; hence our
classification as SAB0 (see Fig. 5).
