Abstract:
    Using the ESO/SERC and POSS-I surveys we selected 76 isolated triple
    systems of galaxies with DE<-3{deg}. For each triplet the
    equatorial coordinates, type of configuration, angular diameters,
    apparent angular separation of the components, morphological types,
    total magnitudes and other characteristics are presented.

Note (1): Isolation criteria:
        + component is isolated,
        - component is not isolated,
Note (2): ESO diameters were translated to the POSS-I diameters
    a(o)=0.8078a(j), b(o)=0.7827b(j)
Note (3): Separations refer to components:
        m_Seq = 'A' : A-B
        m_Seq = 'B' : B-C
        m_Seq = 'C' : C-A
Note (4): Configuration type is indicated as:
      T = Triangle       D = Hierarchical        L = linear
Note (5): \} - means merged identification.
