Abstract:
This paper presents 452 new 21-cm neutral hydrogen line measurements
carried out with the FORT receiver of the meridian transit Nancay
radiotelescope (NRT) in the period April 2003-March 2005. This
observational programme is part of a larger project aiming at
collecting an exhaustive and magnitude-complete HI extragalactic
catalogue for Tully-Fisher applications (the so-called KLUN project,
for Kinematics of the Local Universe studies, end in 2008). The whole
on-line HI archive of the NRT contains today reduced HI-profiles for
∼4500 spiral galaxies of declination delta >-40°
(http://klun.obs-nancay.fr). As an example of application, we use
direct Tully-Fisher relation in three (JHK) bands in deriving
distances to a large catalog of 3126 spiral galaxies distributed
through the whole sky and sampling well the radial velocity range
between 0 and 8000km/s. Thanks to an iterative method accounting for
selection bias and smoothing effects, we show as a preliminary output
a detailed and original map of the velocity field in the Local
Universe.
Description:
We present here the tables 2, 3 and 5 containing respectively:
- the measured HI parameters for 452 spiral galaxies
- the associated comments and complementary informations
- the derived redshift independent distances for 4150 galaxies

Global notes:
Note (G1): Quality code as follows:
A = high quality spectrum, high signal to noise and well
defined HI profile.
B+ = intermediate case.
B = good signal to noise ratio, well defined edges of the line,
width OK for TF applications.
C+ = intermediate case.
C = low signal to noise, noisy or asymmetrical profile, possible
HI confusion but well defined systemic radial velocity.
D = low signal to noise, noisy profile at the limit of detection.
Rejected.
E = not detected.
