Abstract:
    We use a compilation of redshifts of rich clusters by Andernach, Tago
    and Stengler-Larrea (1996, in preparation) to determine superclusters
    of rich clusters up to a redshift of z=0.12. Superclusters were
    searched for with a clustering algorithm, using a neighbourhood radius
    of 24h^-1^Mpc (h is the Hubble constant in units of 100km/s/Mpc).
    The catalogue contains 220 superclusters of rich clusters, of which
    90 superclusters have been determined for the first time. Table A2
    gives the supercluster number, its multiplicity, centre coordinates, a
    list of member clusters and identifications with the catalogue by
    Einasto et al. (1994MNRAS.269..301E).

Note (1): c stands for supercluster candidate, i.e. a supercluster
           in which less than two member clusters have a redshift measured
Note (2): "e" indicates a cluster with estimated redshift
          "-" indicates a cluster which would not be a supercluster
               member if one had used only clusters with measured redshifts
               in the search algorithm
