Description:
    A new identification between Abell and Zwicky clusters of galaxies and
    vice versa is completed.  Two  convenient  files  are  generated  with
    necessary data  for comparing  both catalogs;  remarks on  the cluster
    matching are also included.

Note on Cflag:
     'c' indicates that a comment exists in file azrem.dat
     'n' indicates that no Zwicky cluster exists toward the Abell one.
Note on Code: There are four possibilities:
     '0' : no matching,
     '1' : Abell cluster identical with Zwicky cluster,
     '2' : one Abell cluster is equal to two Zwicky clusters,
     '+' : two or more Abell clusters are equal to one Zwicky cluster.
