1. 2006MNRAS.369..497K
Re:NGC 4660
Similar to NGC 4621, there are strong indications for a disc component in this
galaxy, accompanied by pointy discy isophotes. This galaxy is among the best
examples of Mg b isoindex contours to be flatter than the isophotes for galaxies
with strong rotation.

Re:NGC 4660
This galaxy shows clearly detected [O III] emission, possibly originating from
PNe, in a few spectra, in particular from the southern part of the galaxy. A
nuclear disc is visible in the HST image, as recognized also by Lauer et al.
(2005).

Re:VCC 2000
VCC 2000 (NGC 4660).The center is saturated in the g-band image. The galaxy is
very elongated but becomes boxy at a distance of about 6" (along the major axis)
from the center. At the corresponding distance along the minor axis (4.5"), to
the south, there is a small, faint, very blue structure, resembling a nucleus
with two spiral arms. The "arm" facing the nucleus of VCC 2000 is more extended
and looser than the arm facing away. The entire structure is about 2.5" across.

Re:NGC 4660
NGC 4660: The velocity map shows the superposition of two rapidly
rotating components: an inner one inside 5 arcsec and a thicker
structure outside 7 arcsec. This galaxy was used by Bender et al. (1994)
as a prototype for discy ellipticals, due to its pointed isophotal shape
and the strong h_3_ anticorrelated with V.

There is a disk in the outer isophotes of NGC 4660, yet the
deviations from pure ellipses are subtle enough that the type was
called E5 in the RSA and RC2. It was independently classified as
E3/S0_1_(3) in the Virgo Cluster Catalog (Binggeli, Sandage, and
Tammann 1985) from the same Las Campanas plate shown here. The
near-disk is visible in this negative print as the family of pointed
outer isophotes.

NGC 4660 is in the Virgo Cluster. The globular cluster candidates
in the outer regions are well shown in the negative print here. The
high brightness of the globular cluster candidates suggests that NGC
4660 may be closer than the core of the Virgo Cluster; its brightest
globular clusters are brighter than those in M87.

Re:NGC 4660
Galaxy with a prominent stellar disk along its apparent major axis. The
H{alpha}+[NII] image reveals the presence of ionized gas in the central
region of the disk structure. The presence of associated dust is not
obvious from the B-I image, and this galaxy has not been detected in the
far-infrared. However, the third and fourth order Fourier terms behave
differently in B, V, and I in the inner 6", which has been shown to be a
sensitive indicator for the presence of dust.

Re:NGC 4660
Prominent stellar disk along major axis causing C4 deviations
<~+0.04. PA twists by 7^deg^ near r = 8" causing significant S4
amplitudes. Fourier terms behave differently in B, V, and I in the inner
6", possibly due to dust absorption.
