The primary reason for studying the dynamics of the local supercluster is for use as a local cosmological test (Silk 1974 Ap. J. 193, 525, Peebles 1976, Ap. J. 205, 318). In addit ion, the measurement of the mass enclosed in the local supercluster provides one of the best measurements of the M/L of galaxy systems on very large scales - a test of the hypothesis that M/L increases with radius for galaxy systems and thus a measure of the unseen matter (neutrino?) content of the universe.
