1. 2006A&A...453...27C
Re:UGC 07142
UGC 7142: in a circle of radius 2" Terashima & Wilson (2003) obtained total
nuclear counts of 32.6 in the 2-8 keV range. A power-law model model modified by
absorption was applied to the data obtaining {GAMMA} = 1.66 and N_H_ = 1.5 x
10^20^ cm^-2^.

Re:NGC 4143
NGC 4143. The outer-disc scalelength is from a Sloan r-band image obtained with
the INT-WFC (Erwin et al., in preparation).

Re:NGC 4143
NGC 4143 (inner disk): Erwin (2000); see Erwin & Sparke (2003). Central
velocity dispersion is from Di Nella et al. (1995).

NGC 4143 (LW)
The circumnuclear dust structure is very low contrast, yet at least
three dust spirals are still visible. While no circumnuclear star
formation is visible, the LINER nucleus is visible as a faint, blue
point source.

Re:NGC 4143
NGC 4143: The archival V-band image shows patchy dust obscuration close
to the nucleus, qualitatively similar to the low-level features in our
residual image.

Re:NGC 4143
NGC 4143.-Wrobel & Heeschen (1991) find a 6 cm flux density of 6.7 mJy
at 5" resolution. The similar-resolution (5") FIRST map shows a peak
flux density of 5 mJy beam^-1^ at 20 cm, with extended emission in
P.A. 10^deg^, which is not along the minor axis of the host galaxy.
Combining the FIRST peak flux density with our 2 cm peak flux densities
of 3.3 and 5.3 mJy beam^-1^ at resolutions of 0.15" and 5",
respectively, results in a nonsimultaneous spectral index,
{alpha}_20_^2^ between -0.2 and 0, for all emission within the central
5". Ho et al. (1997b) note that broad H{beta} may also be present in
this object.

Re:NGC 4143
NGC 4143.--As the bases of the [S II] lines are not significantly wider than
that of a single Gaussian, the extended wings of the H{alpha}+[N II] complex
probably signify the presence of a prominent broad H{alpha} component. Indeed,
a four-component Gaussian fit to the complex yields a broad line (FWHM~2100
km s^-1^) containing a large fraction (f_blend_~45%) of the emission
(Fig. 11e). Broad H{beta} may also be present.

Two short, smooth, massive embryonic
arms, seen best in the insert, emerge from the
bulge. Each arm ends within the S0-like disk at
about half the disk radius visible on the main
print. The arms are well seen on the original
plate but are only hinted at in the insert, shown
at the same scale as the main print. To trace the
arms in these prints, it helps to know that the
arms close up counterclockwise as one moves
from their outer tips inward.
The disk has a prototypical S0 morphology.
The galaxy would be classed S0_1_ using
low-resolution and/or heavily exposed plates. The
arms, evident on the present plate material,
would not be detected. This galaxy is one of the
earliest of the transition cases between the pure
S0_1_ and the Sa types in the RSA.

Re:NGC 4143
NGC 4143: The isophotal analysis detects a bar-like feature as implied
by the RC2 classification, i.e. SAB0 (see Fig. 5). There is also a
significant minor-axis asymmetry implying an extended dust layer (see

Small, bright diffuse nucleus. Very weak bar and traces of spiral structure.
