The Coma supercluster: Analysis of Zwicky-Herzog cluster 16 in field 158

Radial velocities for 50 of the 52 galaxies brighter than 15.1 mag within the boundaries of Zwicky-Herzog cluster 16 in field 158 are used to establish that the region is a composite of (i) part of the Coma I cloud of the Local Supercluster, (ii) part of the supercluster of which the Coma cluster is a member, (iii) the NGC 4169 group, and (iv) other galaxies. The Coma supercluster is detected to a radial distance from the center of the Coma cluster of 14degree.2 (31.5 Mpc for H=55 km s-1 Mpc-1)
