C-42 (= NGC 4672): it has an elliptical stellar core rotating
perpendicularly to the disk and appears to be the end result
of the accretion of material in polar orbits in a disk around
a pre-existing oblate spheroid, like in the prototype PRC B-19
(Sarzi et al. 2000). The object was detected in the present
survey, at V_HI_ = 3202 +/- 6 km s^-1^, as well as previously
at Parkes and at Green Bank (see Table 2) at similar velocities,
which are all consistent with the mean optical systemic value of
3346 +/- 63 km s^-1^ (LEDA). The integrated line flux of
7.7 Jy km s^-1^ measured at Green Bank (Paper I) is significantly
lower than the 12.7-15.6 Jy km s^-1^ found at Parkes
(Aaronson et al. 1989, and the present paper). No candidates for
confusion with our H I spectrum were found within the search area:
though NGC 4677, a 13.9 mag object at 10.7' distance, has a
velocity of 3135 +/- 40 km s^-1^ (LEDA), similar to that of the
PRC object, it is well outside the telescope's FWHM and classified
as SB0 and therefore expected to be gas-poor.
ESO 322-G73 is an early-type galaxy with a small disc component, which
shows a clearly disturbed morphology, that may be due to an interaction
with a nearby galaxy in the same group. Apart from the red feature
associated with the in-plane dust lane, the dust-free regions in its
vertical colour profiles are essentially featureless and consistent with
a zero gradient (T = -0.3).
C-42 = NGC 4672. The GB 140' sees 2.8 x 10^9^ M_sun_ of HI, with a
large velocity width, as would be expected if the gas is associated with
the extended edge-on component. NED lists three companions within 10' and
a further eight, many of which are dwarf ellipticals, within 20'. Two of
these galaxies are spirals with radial velocities at the edge of the
observed linewidth, and thus might have contributed to the total HI flux
seen by the GB 140'.
Similar to NGC 5128 with spiral arms, very faint extension.
