Abstract:
The correlation between the maximum rotational velocity of the disk
(vm) and the central stellar velocity dispersion of the bulge (sigma0)
offers insights into the relationship between the halo and the bulge.
We have assembled integrated HI line widths and central stellar
velocity dispersions to study the vm-sigma0 relation for 792 galaxies
spanning a broad range of Hubble types.

Note (1): Defined as C59=5log(rP90/rP50), where rP90 and rP50 are the
Petrosian radii enclosing 90% and 50% of the light, respectively.
Note (2): Isophotal diameters measured at a surface brightness of
µB=25mag/arcsec2.
Note (3): Reference for b/a as follows:

Note (4): Calculated from b/a, as described in the text.
Note (5): Derived assuming a Local Group infall velocity of 208km/s toward
the Virgo cluster and a Hubble constant of H0=70km/s/Mpc. Additional
data come from Rizzi et al. (2006ApJ...638..766R 2006ApJ...638..766R, NGC 300),
Lee et al. (2002ApJ...565..959L 2002ApJ...565..959L, NGC 598),

Note (6): Corrected for Galactic and internal extinction, using the inc and
the formalism of Bottinelli et al. (1995A&A...296...64B 1995A&A...296...64B).
Note (7): Not been corrected for Galactic or internal extinction.
Note (8): Calculated using the following prescription from the RC3,
log(MHI/MSun)=-0.4m21+log(1+z)+2log(Dist/Mpc)+12.3364,
where m21 is the HI "flux" and z is the redshift.

Note (1): Corrected for instrumental resolution, interstellar turbulence,
(1+z) cosmological stretching, and inclination angle. We obtained
MaxVel from either W20 or W50 using the calibration given in
Paturel et al. 2003b; when both W20 and W50 are available,
MaxVel is the average of the two derived values.
Note (2): Assumed to be approximated by the error on the homogenized value of
the rotation velocity given in Hyperleda.
Note (3): Telescope code as follows:
1 = Nancay
2 = Westerbork Sythesis Radio Telescope
3 = NRAO Green Bank 140 foot

8 = Effelsberg 100m
9 = Arecibo
10 = Parkes 64m
14 = Jodrell Bank 125 foot * 85 foot

Note (4): Additional notes as follows:
1 = Faint galaxy in the beam, but unlikely to be a source of confusion
2 = Significant galaxy in the beam, but not a source of confusion
according to interferometric data
Note (5): Sampled numbered as follows (see section 2 of paper):
1 = Primary source of data, with homogenized data from Hyperleda
2 = Galaxies with usable HI data but no velocity dispersion

in 4a, 4b and 4c depending on the origin of velocity dispersions
and maximum rotation velocity
