Abstract:
After a compilation of HI data from 611 references and new
observations made in Nancay, we produce a catalog of homogenized HI
data for 16781 galaxies. The homogenization is made using the EPIDEMIC
method from which all data are progressively converted into the
adopted standard. The result is a catalog giving: 1) the logarithm of
twice the maximum rotation velocity, log2VMsini, converted to the
system of Mathewson et al. (1996ApJS..107...97M 1996ApJS..107...97M). This quantity is
given without correction for inclination; 2) the HI magnitude, m21,
(area of the 21-cm line width expressed in magnitude) converted to the
flux system of Theureau et al. (1998A&AS..130..333T 1998A&AS..130..333T); 3) the HI
velocity, VHI, expressed with the optical definition (i.e., using
wavelengths instead frequencies). The typical uncertainties are: 0.04
for log2VMsini, 0.25mag for m21 and 9km/s for VHI.

Note (1): Quality of the line:
A: nice, high signal to noise, symmetrical, double horn profile,
best data for TF application
B: robust HI parameters for TF application, more noisy than "A" galaxies
C: well detected but noisy profile, generally HI confused, but OK for
radial velocity measurement
D: marginally detected, out of use
