2007A&A...465...71T Kinematics of the Local Universe. XIII. 21-cm line measurements of 452 galaxies with the Nancay radiotelescope, JHK Tully-Fisher relation, and preliminary maps of the peculiar velocity field Theureau, G.; Hanski, M. O.; Coudreau, N.; Hallet, N.; Martin, J.-M. Abstract. Aims. 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. Methods: 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 {delta} > -40^degree^ (http://klun.obs-nancay.fr). Results: 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 8000 km s^-1^. 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. Key words: astronomical data bases: miscellaneous, surveys, galaxies: kinematics and dynamics, radio lines: galaxies
