Re:NGC 2964
NGC 2964, classified as Sbc, forms a non-interacting pair with the I0 galaxy NGC
2968 at 5.8 arcmin. As discussed by Ganda et al. (2006), the SAURON data reveal
that this barred Sbc galaxy hosts an AGN. When we calculate the line strengths,
we find that the Mgb index assumes low values in an elongated central region,
higher values around it, and low values again towards the edges of the field;
the Fe5015 index presents a very similar behaviour; the H{beta} map has instead
an opposite appearance, with an extended inner region with low index values and
a surrounding area with higher values; in the very centre a shallow peak might
be recognized. These features are recognizable also in the profiles in Fig. A2.
We note also that the central region with low Fe5015 and Mgb corresponds to the
central depression in the emission line [O III]/H{beta} map (see fig. 5 in Ganda
et al. 2006), possibly indicating ongoing star formation. Converting the line
strength maps to age and metallicity via our comparison with the SSP models, we
find young-intermediate ages over most of the field, with a peak in the central
region, and low metallicity everywhere, with a minimum in the central region, a
positive gradient out to ~=5 arcsec, and then a rather constant behaviour out to
~=15 arcsec. From the continuous star formation approach, we cannot exclude at
all ages the case of constant star formation, but the {tau} map for age fixed to
10 Gyr (in the fitting procedure) presents a large central region with low
values, possibly suggesting an ~=5-Gyr-long starburst.

Re:NGC 2964
Good S/N with clear rotation and a centrally peaked {sigma}_*_ field. Slight
central peak in the curve of growth. Significant amounts of dust (Hughes et al.
2003). See Figures 11 and 15a.

Re:NGC 2964
The morphological classification as determined by us is indicated in
parentheses next to the galaxy name, with our "chaotic circumnuclear
dust" (C) category now not including those galaxies with obvious dust
lanes (DL). Where the classification has already been made by Martini
et al. (2003), we indicate this with "-mp."

Figure 4 (bottom).
Spectra: Strong emission lines near continuum center, including
obvious [S II] emission lines. Continuum is generally weak.
Images: Carollo et al. (2002) find a spiral structure and red dust
features down to the nucleus. In these images we see a possible ring
or spiral structure obscured by significant amounts of dust, as
demonstrated in the color map.

Re:NGC 2964
NGC 2964.---SABb (pec): Slightly elliptical bulge, with possible
evidence of a weak bar oriented close to bulge minor axis. Four-armed
spiral pattern, with two arms emerging from ansae at the bar ends, and
two others emerging near the center of the bar. Arms are irregular,
with the outer disk having roughly rectangular isophotes. The two
arms coming off the bar ends (the north and south arms) are of higher
surface brightness than the other two. There is some evidence for
bright knots in all but the west arm.

Spiral structure and red (dust) features down to center; reddened nucleus?

Re:NGC 2964
13. NGC 2964 is an Sc galaxy with strong massive arms. It may form a
physical pair with the S0 galaxy NGC 2968 at a separation of 6.2'
(Sandage & Bedke 1994). However, the spiral pattern is fairly regular.

NGC 2964 may form a physical pair with
NGC 2968 (Amorphous or S0_3_ pec; panels 49,
337), at an angular separation of 6.2'. The
redshifts are v_o(2964) = 1292 km/s and
v_o(2968) = 1576 km/s. If they are associated
at a mean redshift distance of 29 Mpc (H = 50),
the projected linear separation of the pair is
small at 52 kpc, which is the distance of the
Large Magellanic Cloud from the Sun.
The arms in NGC 2964 are massive in the
sense of Reynolds (1927a,b). The pattern is
principally that of two arms, although a third,
ill-defined broad arm pattern exists on one side.
Opaque dust lanes exist on the insides of the two
best-defined luminous arms.

NGC 2964 forms a close physical pair with

at a separation of 5.8'. The redshifts are
v_o(2964) = 1292 km/s and v_o(2968) = 1576
km/s. At the mean redshift distance of 29 Mpc
(H = 50) the projected linear separation is small,
at 49 kpc.

Re:NGC 2964
NGC 2964 is an Sc galaxy previously detected by S88 at KP at an intensity
three times below ours which implies a source size smaller than our 23"
CO( 1-0) beam. Our CO spectra show a double peak centered precisely on
the HI velocity. This probably indicates either a nuclear ring too small
for us to distinguish and/or a sharply rising rotation curve reaching
turnover within the beam. The two transitions are in close agreement. H87
find a central source in radio continuum at 6 cm and 20 cm and Keel
(1985) found a strong H{alpha} line with a large equivalent width. This
is rare among our sample galaxies.
