1. 2006ApJS..164..334F
Re:VCC 0654
VCC 654 (NGC 4340), The galaxy is quite round within the inner 1.7", beyond
which it becomes stretched in the northeast-southwest direction, due to the
presence of an inner bar surrounded by a nuclear stellar ring. Beyond 6", the
galaxy is elongated in the east-west direction. The very innermost region
(within 0.5") is also elongated, in the same direction as the outer parts. From
the color image, the innermost structure appears bluer than the main body of the
galaxy. An outer stellar ring with semimajor axis of about 56" bounds an outer
bar; a small irregular galaxy lies along this ring about 40" to the northeast of
the center.

Re:NGC 4340
NGC 4340. All measurements are from MDM R-band images (bar measurements agree
very well with J- and K-band measurements from BARS Project images), except for
the outer-disc scalelength, which is from the R-band image of Frei et al.
(1996).

Re:NGC 4340
NGC 4340. In the optical region this galaxy has been classified as a double
barred system by Erwin (2004), the secondary bar being surrounded by a nuclear
ring. Both bars are identified also in our K_s_-band image, by all indicators of
a bar. The secondary bar is aligned with the primary bar, which deviates from
that of the underlying disc. This galaxy has also a nearly spherical bulge and
an oval inside the primary bar.

Re:NGC 4340
NGC 4340. This is again an example of a galaxy with a complicated structure
having two bars and a lens, which were all fitted in the final decomposition. As
usual, the solution was found in steps starting from the parameters of the disc
and the primary bar, and then finding the parameters for the bulge and the
secondary bar. Again, the ansae-type morphology of the bar is visible in the
residual image.

Re:NGC 4340
NGC 4340: Kormendy (1979) and Wozniak et al. (1995). Bar and outer-disk
measurements are from an MDM R-band image obtained by Paul Schechter;
inner-bar L_bar_ is from size of stellar nuclear ring; see Fig. 3 and
Erwin et al. (2001). The distance is the default Virgo Cluster distance
(see note for NGC 4262).

6. 1996A&AS..118..461F
Re:NGC 4340
NGC 4340. The innermost structure regarded as a secondary bar in Paper I seems
to be also present in JH-images (K-band is saturated). It is roughly aligned in
projection with the primary bar ({theta}_13_ ~ -3^deg^). The J - H colour map
displays a blue central region (J - H ~ -0.1) as compared with the rest of the
primary bar (J - H ~ 0.1).

NGC 4340 is one of the best examples of the
form described on this page for NGC 3892 and
NGC 4371 as an enhancement of the ring at the
edge of the disk at the two termination points of
the bar. Note here, as in NGC 3516 and NGC
4371 above, the two areas of decreased
luminosity at position angles of about 2:30 and
8:30 o'clock on the facing print. Athanassoula
(1984) attributes these regions of decreased
luminosity to a sweeping-out of material by
dynamical processes associated with the L3
Lagrangian points. As it is a common feature in
barred galaxies, and as it occurs at the same
positions relative to the bar in these galaxies, one
suspects that the phenomenon is a dynamical
effect associated with the bar.
