Study of galaxies from 21-cm line : I-General catalogue of 21-cm line data.
New observations of the 21-cm line of about 400 galaxies and a general compilation of published 21-cm line profile are combined to form a catalogue of 21-cm line widths at three levels, HI fluxes and radial velocities (1795 entries).
The different corrections on line-widths, fluxes and velocities are derived and applied to produce a homogeneous catalogue of properly weighted averages of the corrected data for 1207 galaxies.
This catalogue will be used in subsequent papers for several applications, including the extragalactic distance scale, the local velocity field, the Hubble constant and the physical properties of galaxies.
