Scientific paper

Crude estimates are given for the mean extension in depth of the two large supercluster structures, Coma-A1367 and Perseus/Pisces. These superclusters were judged favorable subjects for such measurements due to the running of their longest dimension in an approximately perpendicular direction to the line of sight. It is assumed that the Hubble flow is dominant along the shortest dimension, although this may be true only at large distances from the density peak. Preliminary estimates are a mean width of about 14 Mpc and mean depth of about 16 Mpc for Coma-A1367, while the two dimensions for the case of Perseus/Pisces are 12 and 24 Mpc, respectively.
