We got HST/STIS long slit data for NGC 4435 ([NII] emission line) along 4 slit positions

STIS acquisition images for NGC 4435 with the slit position superimposed and the centre marked with a white cross.

We performed a 3D model according to the following scheme... (The slit along the minor axis is not drawn just for clarity, but it has been obviously taken into account)

RESULTS:

Observed [NII] kinematics (filled circles) along with the best-fitting model (solid line) and 
model predictions for the SMBH masses of NGC 4435&nbsp; from the M_smbh- sigma relation 
by Ferrarese & Ford (2005, M_bh = 5e7 Msun, dotted line) and from the near-infrared 
M_bh-L_bulge relation by Marconi et al. (2003, M_smbh = 4e7 Msun , dashed line). The observed 
and modeled velocity curve (top panel), velocity dispersion radial profile (middle panel) and flux radial 
profile (bottom panel) are shown for slit along the major axis (slit #1, {upper left panels), close to minor axis 
(slit #4, upper right panel), along eastern offset (slit #3, lower left panel), and western 
offset (slit #2, lower right panel)
