Abstract:
Based on the modeling of the central emission-line width measured over
subarcsecond apertures with the Hubble Space Telescope, we present
stringent upper bounds on the mass of the central supermassive black
hole, M{blackhole}, for a sample of 105 nearby galaxies (D<100Mpc)
spanning a wide range of Hubble types (E-Sc) and values of the central
stellar velocity dispersion, σc (58-419km/s).
Description:
In order to assemble the largest possible sample of homogeneous
measurements of the central emission-line width, we queried the HST
Science Archive for objects with STIS spectra obtained with the G750M
grating through either the 0.1"x52" or the 0.2"x52" slit placed across
the galaxy nucleus, most often at random position angles. This is
indeed by far the most common configuration in the archive, which
always gives us access to the [NII] λλ6548,6583,
Hα, and [SII] λλ6716,6731 emission lines.
Limiting ourselves to galaxies within 100 Mpc to minimize the impact
of the stellar potential on our results, we retrieved data for 177
galaxies spanning the whole range of morphological types.

Note (1): From Ho et al. (1997, Cat. J/ApJS/112/315 and 1997ApJS..112..391H 1997ApJS..112..391H),
where H = HII nucleus, L = LINER, S = Seyfert, T = transition object
(LINER/HII), 1 = type 1, 2 = type 2, and a fractional number between 1
and 2 denotes various intermediate types; uncertain and highly uncertain
classifications are followed by a single and double colon, respectively.
Note (2): All the distances were taken from literature (see refs.dat file),
except those we obtained from V3K, the weighted mean recessional velocity
corrected to the reference frame of the microwave background radiation
given in RC3. These were derived as V3K/Ho with Ho=75km/s/Mpc.
Note (3): All the effective radii were taken from literature (see refs.dat
file), except for those we measured by a photometric decomposition of the
K-band images available in the 2MASS science archive Skrutskie et al.
(2006, Cat. VII/233).
Note (4): Reference for the measured stellar velocity dispersion and
corresponding size of the central aperture from which we calculated the value
given in sig.c by following Joslashrgensen et al. (1995MNRAS.276.1341J 1995MNRAS.276.1341J).
We did not apply any aperture correction to the measured stellar velocity
dispersions of NGC 2748, NGC 3982, and UGC 1841, because no information
about the size of the aperture was available.
Note (5): This is the intrinsic velocity dispersion obtained from the observed
one by subtracting the instrumental velocity dispersion.
Note (6): The MBH of NGC 3227 and NGC 4258 were obtained by studying the
dynamics of stars and water masers, respectively. The ionized-gas dynamics
was used for all the remaining galaxies.

the [NII] emission line
n = faint or absent emission lines
p = double-peaked emission lines
