Re:NGC 0613
NGC 613 (Fig. 5c).-There exists a small partial nuclear ring containing 11
individual star-forming H II regions with a strong nucleus. A fairly flat
distribution in the log (EW) appears around the entire ring with ages averaging
no less than 10 Myr. The galactic bar is located at PA = 110^deg^ along its
major axis. Although a gradient is not defined, one of the contact points (at
200^deg^) coincides within 5^deg^ to the youngest hot spot (PA = 205^deg^ ) in
its respective hemisphere.

Re:NGC 0613
Clearly defined rotation despite a high level of discordance. The {sigma}_*_
field is patchy but a significant difference between extended and central
values of {sigma}_*_ is noted. There are also significant values of h_3_
and h_4_ corresponding to a central asymmetric non-Gaussian LOSVD. See
Figures 4 and 10a.

Re:NGC 0613
NGC 613: Suggested as double-barred by Jungwiert et al. (1997), using their
H-band image. Inspection of WFPC2 images reveals a pronounced and very
elliptical nuclear ring with strong star formation, having the same size,
ellipticity, and orientation as the suggested inner bar. While unsharp masking
of the H-band image (courtesy Francoise Combes) displays something like an inner
bar feature, the bright ends of the "bar" are resolved into multiple star
clusters in the HST images. This indicates that the feature is probably not an
inner bar, but higher-resolution near-IR (preferably K-band) images are needed
to decide one way or the other.

Re:NGC 0613
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 1 (bottom).
Spectra: The continuum is generally weak; there is large-scale
extended patchy emission with broad emission lines in OFF 2 and NUC
spectra. In the NUC spectrum the broad feature appears to be located
.4" from the principal continuum.
Image: Hummel & Jorsater (1992) found from Very Large Array
observations that NGC 613 has a complex nuclear geometry when observed
in radio emission. They found a central elongated region of three
distinct components ~300 pc in length (assuming a distance of 19 Mpc
to the galaxy). They also found an arc feature ~350 pc from the
nucleus.

Re:NGC 0613
NGC 613.---SB(r)bc (type example---see Fig. 3f ): Bright nuclear point
source. Nuclear bar aligned with elliptical bulge and large normal
bar. Fairly highly inclined disk. Two bright arms emerge from the ends
of the bar, with many bright knots near the bar ends. SE arm wraps
loosely to the NE. NW arm wraps tightly to the SW and forms an inner
disk ring. Several other, lower surface brightness arms emerge from
the ring.

Re:NGC 0613
NGC 613 (SBbc/Seyfert, 1"~86 pc, I=35.1^deg^)
This Seyfert galaxy is known to possess, inside the large-scale bar, an optical
nuclear spiral. BC93 give semi-major axes of the feature 7x6". We identify
short nuclear spiral arms also in the near-IR and suggest, on the basis of both
the ellipse fitting and the inspection of the grey-scale image, that they have
an associated nuclear bar (e_max_^s^=0.55 at a=5.3"). If our interpretation
is correct, then NGC 613 is a new example of a double-barred system. The
primary bar peaks (e_max_^p^>0.72) outside our image.

Re:NGC 0613
In NGC 613, line ratios measured by Osmer et al. (1974) indicate a "transition"
spectrum. Observations around H{alpha} with a resolution of ~180 km s^-1^ show
that it is a composite spectrum (Veron-Cetty & Veron, 1986b).

8. 1996A&AS..115..439E
Re:NGC 0613
NGC 613 is a barred spiral galaxy with an active hot spot nucleus, a radio jet
and a circumnuclear radio ring; there is some evidence for an accelerated
collimated outflow (Hummel et al. 1987).

Re:NGC 0613
Several components can be identified on the optical image of this galaxy
which was classified as SB(rs)bs by deVaucouleurs et al. (1991, RC3).
Starting from the nuclear region, prominent dust lanes run along the bar.
H II regions and emission knots are also present along the bar as well as
along the bright inner arms which form a pseudo ring whose orientation is
the same as that of the bar. The fainter outer arms follow also this
orientation which seems to indicate that the position angle of the galaxy
as a whole is close to that of the bar.
The most active star forming regions appear to be at the ends of the
bar. Burbidge et al. (1964) obtained optical spectra of H{alpha}, [NII]
and [SII] on the nucleus and outer knots of NGC 613. The velocity curve
derived from these spectra, using a PA of 115^deg^, is steep and
symmetrical in the central region, with a total velocity range of 450 km
s^-1^. In the outer regions the curve is asymmetric with anomalous
features. These results were confirmed by Blackman (1981).
Hummel & Jorsater (1992) and Saikia et al. (1994) present high
resolution radio continuum maps of the central kpc of the galaxy. Global
velocity profiles in the HI line were obtained by Bajaja (1979) (B79) and
Reif et al. (1982) (RMGWS82).

The bar in NGC 613 is a strong
(high-surface-brightness) oval. The characteristic
two straight dust lanes on opposite sides of the oval
are evident. Each lane is on the leading edge of
the oval as judged from the direction of rotation
determined by the sense of the spiral pattern.
Other dust lanes at the outer boundary of the
oval are curved into spiral patterns at sharp
pitch angles which differ from the pitch angles of
the outer spiral arms. The various patterns of
inner luminous arms and inner dust lanes have a
striking resemblance to maps of velocity fields
based on calculations of the hydrodynamic
response of gas to the rotating bar (or oval)
gravitational potential, as cited in the description
of NGC 1300 (compare Huntley 1980 with earlier
references).
The high surface brightness of the arms and
the many HII-region candidates show a
moderate-to-large current star-formation rate.
The largest HII regions resolve at the 3" level.
The redshift of NGC 613 is v_o = 1534 km/s.
The absolute magnitude is bright, at M_B_ = -22.2
(H = 50).

Re:NGC 0613
A very interesting {phi}-type spiral about 4' long. It somewhat resembles
NGC 1300 and NGC 5921. The nucleus is pear-shaped; there are numerous rather
hazy condensations. The nucleus is quite bright. A faint oval patch of
nebulosity lies 21.5' to the south. 5 s.n. .
