Re:NGC 4245
NGC 4245 is a barred galaxy with a prominent dust ring in the centre (Erwin &
Sparke 2003). The stellar velocity field is misaligned with respect to the bar
major axis. There is also evidence, in the stellar kinematics (V, {sigma},
h_3_), for a central disc in the inner 5 arcsec. A circumnuclear ring is
particularly evident in the H{beta} flux map. The correspondingly low values of
the H? velocity dispersion and [O III]/H{beta} ratio suggest that star formation
is taking place at the same location.

Re:NGC 4245
NGC 4245. Outer disc orientation and scalelength measurements are from a Sloan
r-band image obtained with the INT-WFC (Erwin et al., in preparation).

Re:NGC 4245
NGC 4245. In RC3, this galaxy is classified as a barred galaxy with an inner
ring. ES03 found a nuclear ring in the R band, but no evidence of a secondary
bar in the optical HST image. ES03 also report dust lanes in the inner ring
leading into a nuclear spiral that continues into the nucleus. The nuclear ring
at r= 5 arcsec is visible also in our unsharp mask of the K_s_-band image (Fig.
5). NGC 4245 has an oval surrounding the secondary bar.

Re:NGC 4245
NGC 4245. This galaxy has two bars and a lens. The best solution was found in
steps by fitting first the bulge, the disc and the main bar. However, it was
more difficult to fit the lens, which easily disappeared, so that it was not
fitted in the final decomposition. The lens in this galaxy has a low surface
brightness and does not affect the obtained B/T ratio. The model-subtracted
image shows positive residuals at the ends of the bar, hinting at the presence
of ansae.

Re:NGC 4245
NGC 4245. - No radio source associated with this H II nucleus was
detected on the untapered or tapered maps. Neither NVSS nor FIRST has
detected this object at 1.4 GHz.

NGC 4245 is an early example of a galaxy
form that has caused much confusion in the
literature and has led to unwarranted
conclusions concerning dynamics of rings and
pseudo-rings. Except for the bar, the form for
NGC 4245 here is the same as has been
described in the Sa section, where the near-ring
galaxies have been set apart on panels 66-71.
Spiral arms spring from the ends of the bar
in a manner similar to that in the SBb(s)
prototype NGC 1300 (Hubble Atlas, p. 45;
panels 154, S8 here). But the arms here are so
tightly wound and the inclination to the line of
sight is so great that the two opposite arms
appear to almost overlap after each has unwrapped
by a half turn.
On casual inspection this near-overlap
appears to be a complete ring. Sometimes, when the
pattern is less subtle than here for NGC 4245 or
for the closely similar case of NGC 5750 (SBa;
panel 98), the pattern has been called a broken
ring. Examples of these less-subtle cases are NGC
3081 (SBa; Hubble Atlas, p. 11; panels 99, 107
here), NGC 2217 (SBa; Hubble Atlas, p. 43;
panels 101, 104, 107 here), and NGC 3185
(SBa; Hubble Atlas, p. 43; panel 99 here).
These examples are of the (s) NGC 1300
spiral subtype. None have internal rings, broken
rings, or pseudo-rings. The distinction, of course,
is difficult to make on low-resolution plate
material. When using such material, the finer
subclassifications of (s) and (r) will often be
