Abstract:
The structure of the Hercules and Perseus superclusters has been analysed by the non-hierarchical-descendent taxonomical method. In the case of Hercules, well-defined groups are present. The membership of the galaxies with respect to the groups is given, as well as the physical parameters for the groups. A morphological type-redshift effect is present. For Perseus, the internal structure is much less well defined, as it appears as a filamentary aggregate without a clear subgrouping. Tentatively some apparent groups in it are noted and its physical parameters calculated.
