Abstract:
Radio continuum observations made with the Westerbork Synthesis Radio
Telescope at 1.4GHz are presented for 274 galaxies in the Virgo
Cluster region. The observations are partly full syntheses and partly
east-west strip distributions. For the 55 detected galaxies the
emission is separated into central and extended components. A brief
summary of the analysis is also given.
