Abstract:
The radio continuum radiation at 1415MHz of 450 galaxies was observed
with the Westerbork Synthesis Radio Telescope. 190 galaxies were
detected. The survey provides data on the total intensity and on the
structure of the radiation. The detection limit for point sources is
10mJy and the resolution is about 23" on average.

Note (1): In order of preference the group velocity as given in
de Vaucouleurs (1975, in Stars and Stellar Systems, Vol. IX, Univ. of
Chicago Press, Chicago), the corrected radial velocities from the RC2
(1976, Cat. VII/112) and the radial velocities as given by Sandage
(1978AJ.....83..904S 1978AJ.....83..904S, indicated by *) were used.
For a small number of galaxies (n_Dist=?) the distances were
estimated from BTmag and D0 versus distance plot. The uncertainties
in these distances are quite large.
