Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS                      
  Title: OBSERVATIONS OF THE SHAPLEY SUPERCLUSTER                                        


Abstract:
 We propose ASCA observations of 3 member clusters of the Shapley supercluster. The
 clusters are chosen to investigate the influence of richness (mass), and position
 within the supercluster, and to determine whether cluster properties, such as the
 efficiency of galaxy formation, are a function of the local overdensity at the time of cluster formation.
