Abstract (from CDS):

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 an exhaustive and magnitude-complete HI extragalactic catalogue for Tully-Fisher applications (the so-called KLUN project, for Kinematics of the Local Universe studies, to end in 2008). The whole on-line HI archive of the NRT today contains reduced HI-profiles for 4500 spiral galaxies of declination δ>-40° (http://klun.obs-nancay.fr). As an example of this application, we used the direct Tully-Fisher relation in three (JHK) bands in deriving distances to a large catalogue of 3126 spiral galaxies distributed through the whole sky and sampling the radial velocity range well between 0 and 8000km/s. Thanks to an iterative method accounting for selection bias and smoothing effects, we show a detailed and original map of the velocity field in the Local Universe as a preliminary output.
