Re:NGC 3941
NGC 3941. This galaxy is classified as a double barred system by ES03 in the
optical region. In the K_s_ image, the main bar has ansae-type morphology and
all the characteristics of a bar. However, the unsharp mask shows that the inner
elliptical is rather an inner disc showing two-armed spirals (Fig. 5). Both the
inner disc and the bar appear as minima in the q profile and are identified as
intensity peaks in the Fourier analysis. This galaxy has also an oval inside the
bar.

Re:NGC 3941
NGC 3941. For this galaxy the parameters for the disc and the bar were found
first, and then they were fixed and the parameters for the bulge and the lens
were found simultaneously. A test was also made of how much omission of the lens
might affect the relative mass of the bulge. We found that the decomposition
including the oval gives B/T= 0.17, while the decomposition without a lens gives
B/T= 0.22. In such a decomposition model the residuals are extremely small.

3.4 NGC 3941
Only one ULX has been detected in this galaxy at 38'' from the centre.
The spectrum is well fitted with a PL model with {GAMMA}=1.9 +/- 0.2
({chi^2^=17.8, {nu} = 19) or a BR model with kT = 4 +/- 2 keV
({chi^2^=24.4, {nu} = 19). In the first case, the flux is
1.7 x 10^-13^ erg cm^-2^ s^-1^ and the luminosity is 7.4 x 10^39^ erg s^-1^.

Re:NGC 3941
NGC 3941 (S2:). - Marginally detected at 6 cm but not at 20 cm.
Wrobel & Heeschen (1991) placed an upper limit of 0.5 mJy in a 6 cm map
made with {DELTA}{theta} = 5".

Re:NGC 3941
NGC 3941. The counterrotating extended gas disk found in NGC 3941 is likely
the result of a merger event or accretion of gas with oppositely directed
angular momentum. The low velocity dispersion found throughout the gas disk
suggests that it has settled into an equilibrium configuration. The minor-axis
rotation of the gas in NGC 3941 is presumably related to the stellar bar.

NGC 3941
NGC 3941 contains a prominent bar, misaligned ~ 15" with respect to the major
axis. An extended gaseous disk, counterrotating with respect to the stars, has
been detected in [O III] 5007 A (Fisher 1994a).

The central bulge, the bar, and the outer
envelope of NGC 3941 all have different position
angles to their major axes. The major axis of the
bulge is at position angles of 12:30 and 6:30 in
the print here.
The bar is moderately distinct, yet massive,
giving an SB0_1/2_ transition bar subtype. The
ansae that define the end of the bar terminate
inside the envelope near the edge of the disk (the
lens, in the language of the Hubble Atlas) at
position angles of about 3:30 and 9:30 o'clock.
This is a common form, present for example in
NGC 7155 (SB0; panel 56), the three galaxies on
the next panel (NGC 936, NGC 1533, and NGC
4477),and NGC 6942 (SBa; panels 92, 106) as
prototypes.
The edge of the low-surface-brightness
extended disk has two bright "rim segments" at
opposite directions from the center, nearly in line
with the position angle of the axis of the central
bulge. The most conspicuous of the arc brightenings
occurs on the lower rim between position
angles of about 6 and 8 o'clock on the print here.
It is very subtle and is best seen by viewing the
print from a distance; the features are definite on
the plate. But these two opposite-rim brightenings
are, in fact, connected to the ends of the bar,
forming "massive" arms. The sense of the arm
pattern is counterclockwise, moving from the
outer tips inward through the disk. This asymmetry
in the outer envelope luminosity distribution
is the reason for the transition classification
of SB0/a rather than simply SB0.
