Re:UGC 06537
UGC 6537. The rotation centre has been assumed to be the strong nucleus, leading
to an asymmetric rotation curve in the outer regions, compatible with the
asymmetric velocity field. In Paper III, in order to get a symmetric rotation
curve, the rotation centre had been shifted by 7 arcsec (~0.5 kpc) with respect
to the nucleus, and the major axis position angle rotated by 6^deg^.

Re:UGC 06537
4.11 UGC 6537 This barred galaxy (SABc), member of the Ursa Major
cluster (Tully et al. 1996), is larger than the field of view of GHASP
and most of its external parts have been cut. It is very rich in ionized
gas, with H{alpha} emission in the bulge surrounded by a ring. The
isovelocities map betrays the kinematical signature of the ring and of
the arms. The centre of rotation is offset from the nucleus by about 7
arcsec; the rotation curve is quite regular and symmetric and reaches a
plateau of 160 km s^-1^ at 90 arcsec. Sanders & Verheijen (1998) have
derived an H I rotation curve at Westerbork in agreement with ours. The
H I map of WHISP shows a hole in the distribution of neutral gas in the
centre and a warp in the outer parts, beyond the optical limit of the
galaxy.

Re:NGC 3726
NGC 3726.---SB(r)bc: Nuclear point source embedded in small very
elliptical bulge. Bulge is threaded by long, prominent bar. The bar
ends at an inner ring. The P.A. of the ring is skewed by ~30deg from
the bar major axis. Three spiral arms emanate from the ring, with the
north arm being the best defined. It can be traced for ~150deg. The
south arm is the brightest and contains the majority of the
star-forming knots. It is very broad at its base and not well defined.
It fades after only ~90deg, but an LSB extension can be traced for
another ~90deg. The third (east) arm is very patchy and diffuse. After
emerging from the east side of the ring, its inner portion proceeds in
a nearly straight line to the NNW and then bends sharply after ~90deg.
The bend is a ~140deg turn to the SW. There are several bright knots
on this part of the arm. The rest of the arm forms a very broad LSB
feature to the north and NE of the galaxy. Because of this, the
system is very asymmetric at low surface brightness levels.

Re:NGC 3726
26. NGC 3726 is an Sbc spiral of medium inclination. It has a small weak
bar (Martin 1995). Nevertheless the fit was satisfying and lead to good
residua (Fig. 5 in on-line version).

NGC 3726, with a redshift of v_o = 909 km/s,
may be kinematically related to the much
smaller nearby galaxies NGC 3769 (SBcII; panel
311) with v_o = 791 km/s, and NGC 3782
(SBcdIII; panel 328) with v_o = 785 km/s. The
angular distances of these two galaxies from
NGC 3726 are 68' and 69', respectively. With a mean
redshift distance of 17 Mpc (H = 50), the
projected linear separations of these nearby
galaxies from NGC 3726 are 336 kpc and 341
kpc - about half the diameter of the Local Group.
The spiral pattern in NGC 3726 is more
disordered than in the Sbc I and I-II galaxies of
earlier luminosity class shown on preceding
panels. The arms are thick, although each are
well-enough defined to be traced as continuous
segments for about half a revolution despite the
branching from the main arms into outer fragments.
The luminosity class is late II.
The largest of the numerous bright HII
regions resolve into core plus halo diameters of
about 4". At a redshift distance of 17 Mpc, this
size corresponds to a linear diameter of 330 psc,
consistent with the calibration of linear HII sizes
as a function of luminosity class given elsewhere
(Sandage and Tammann 1974a).

Re:NGC 3726
Small, very bright nucleus. (r): 1.4 arcmin x 0.75 arcmin. Several partially
resolved bright massive arms.
B(0) source is bright, rejected (wrong identification?)

Bright stellar nucleus; whorls are somewhat irregular, open, and show many
almost stellar condensations. {phi}-type at center. 18 s.n.
