FURTHER ANALYSIS OF A COMPLETE SAMPLE IN THE VIRGO SUPERCLUSTER OF GALAXIES

In the context of the Local (Virgo-centred) Supercluster of galaxies, a statistical study is made of the radio-derived properties for the 16 5 spiral and irregular galaxies in the recently published 'Complete Sa mple' by Fitt & Alexander. I find a trend for a larger neutral hydroge n mass in spiral galaxies located farther from the plane of the Local Supercluster (or smaller H I mass in spiral galaxies closer to the Loc al Supercluster plane). A previously known result, of a deficiency of H I mass in spiral galaxies located radially close to the centre of th e Virgo cluster, is seen again in the ''Complete Sample'. Contrary to some theoretical predictions, the magnetic field strength in spiral ga laxies does not seem to be well correlated with the star-formation eff iciency or the neutral hydrogen mass.
