Re:NGC 1291
NGC 1291: This early-type galaxy does not have enough detected ionized
gas for detailed kinematical mapping. In fact, only nine H II regions
distributed in a ring-like structure can be seen in the H{alpha}
monochromatic and RV maps. The velocity range corresponding to these H
II regions (835-855 km s^-1^) is comparable to what is seen in H I
observations, where the gas is distributed in a bright ring surrounding
a large central hole devoid of gas (van Driel, Rots & van Woerden 1988),
typical of what is seen in the bulge-dominated region of most early-type
galaxies. The H I velocity field of this face-on galaxy looks quite
regular and the associated rotation curve is essentially flat.

Re:NGC 1291
HIPASS J0317-41 (NGC 1291).This large face-on SB0 has a distribution of faint H
II regions which trace tightly wound arms or pseudo ring at r = 4.7". A swirling
pattern of DIG dominates the central H{alpha} morphology. This structure is
devoid of H II regions and increases in surface brightness toward the nuclear
region, reminiscent of the DIG in the bulge of M31 (Ciardullo et al. 1988). The
measurements of this galaxy are difficult because the nucleus is saturated in
the R band (hence, the nucleus is masked from our image) and the galaxy's sparse
population of H II regions extends to the edge of the frame or beyond.

Re:NGC 1291
ULX1 (IXO 6) is located on the outer ringlike spiral arm of this barred S0/a
spiral galaxy, for which the distance is 8.6 Mpc.

Re:NGC 1291
NGC 1291 (HIPASS J0317-41) is a large, nearly face-on, early-type spiral
galaxy of type SBa. Mebold et al. (1979) and Reif et al. (1982) measured
an integrated H I flux density of 72.5+-5.9 Jy km s^-1^, slightly lower
than our measurement of F_HI_ = 90+-12 Jy km s^-1^. Using VLA H I data,
van Driel et al. (1988) show that the H I gas is concentrated in an
annulus (diameter >= 10') extending well beyond the optical bar.

Re:NGC 1291
NGC 1291: de Vaucouleurs (1975); de Vaucouleurs (1974). Outer-bar
measurements are from the DSS2 red image, except for bar PA from Buta
(1995). Inner-bar measurements are from an I-band image (courtesy
Oak-Kyung Park). Disk inclination is from H I kinematics (van Driel
et al. 1988); the disk PA is undefined.

Re:NGC 1291
NGC 1291 (Fig. 1, bottom).--The H{alpha} distribution is diffuse and
spiral-like in the bar/lens region; this region is not covered by the field
studied by Caldwell et al. (1991). The morphology in the bar/lens region is not
obviously correlated with the optical structure. Weak H{alpha} arms extend
beyond the inner lens. Discrete H II regions are found mainly in the outer
ring, which extends beyond the boundaries of the field. The emission near the
center is asymmetric (see Fig. 12), and there is some slight core saturation.
None of the other galaxies in our sample show the complex structure of ioruzed
gas as in NGC 1291, but also most of the other galaxies do not appear to be as
bulge-dominated as NGC 1291. More information on the diffuse emission in
NGC 1291 is provided in section 5.

NGC 1291 has the same pattern as NGC 1543, NGC 2217, NGC 5101,
NGC 5701, and others shown on this and the next few panels. It,
together with NGC 1543, below to the left, is one of the earliest of
these examples. The outer near-ring is of very low surface
brightness. The low-contrast image is printed here to show the bar and
the inner disk region, not the faint outer arms. A high-contrast
negative image, printed to show these outer arms, is shown on panel
102.
The bar is diffuse. It is not well defined on the original
plate. The surface brightness of the central regions is so high that
the inner isophotes are lost in the print here, giving a false
impression of good definition to the bar which, in fact, is ill
defined.
Weak dust lanes exist in the bar, organized in a circulation
(spiral) pattern whose sense is clockwise when moving from the inside
of the image outward. This is the same sense as in the outer spiral
arms whose sense can be seen in the high-contrast image on panel
102. The pattern of the dust is clearly controlled by rotation.

The central disk and bar of NGC 1291 are burned out here, but the
very-low-surface-brightness outer arms and the low-intensity region
between the edge of the inner disk and the arms show well at this
contrast.
The regions where the outer arms connect (if at all) to the inner
disk are indistinct. The high-luminosity disk positions just outside
the edge of the inner disk where connections are probable are at
position angles of about 3:30 and 9:30 o'clock in the print here.
A small but finite recent star-formation rate is evident in part
of the outer arms, shown by the few knots (presumably HII regions) in
these thin-armed fragments.
As mentioned in the previous descriptions of other barred
galaxies, the two regions of lowest surface brightness in the
intermediate disk are just outside the edge of the
high-surface-brightness inner disk. These regions are always at right
angles to the direction of the bar. (See the bar orientation on the
low-contrast print, panel 100.) Athanassoula (1984) writes that this
pattern is predicted from the theory of the interior dynamics of
barred spirals.

(R)SB(s)0^+
(Plate 12)
Fairly large nucleus on weak bar, marking the major axis
of a little, elongated, bright lens.
Faint outer ring structure from which emerge two very weak
spiral arms or arcs.
No ring structure is seen in the lens.
Compare with NGC 7079 (Plate 9), NGC 1617 (Plate 10)
and NGC 2859 (Plate 16).
