Abstract:
Using the ESO/SERC and POSS-I surveys we selected 76 isolated triple
systems of galaxies with DE←3°. 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. The references are:
