Description:
   This catalogue presents data on multiple and double systems, discovered
   as a result of the search in 13 T-associations (Aur T1, Cep T1, Cep T2,
   Oph T1, Sco T1, Ori T1, Ori T2, Ori T3, Ori T4, Tau T1, Tau T2, Tau T3,
   Tau T4), located at the distance of up to 500 pc, are given. As it is
   generally accepted it is considered that the following types of
   irregular variable stars to belong to T-associations: IA, IN, INA, INB,
   INT, UVN, INS, UV, INBS, INTS.

   The search for multiple and double stars was carried out on Palomar
   atlas maps as described in G.N.Salukvadze's paper (Salukvadze, 1980).
   The 670 stars, around which the search has been carried out, are taken
   from catalogues of variable stars (Kukarkin B.V. and others, 1971). In
   13 T-associations 168 double and 134 multiple stars were discovered. Out
   of 134 multiple ones, 120 satisfy the definition of trapezium-type
   multiple systems. Thus, the present catalogue includes 168 double and 14
   multiple stars.

   Following data on multiple and double stars are given in the catalogue:
   name of the main star and data on it (right ascension and declination
   for the year 1900, magnitude, spectral class), type of irregular
   variable stars; positional angles and distances of the components
   relative to the main star, magnitudes and colour indices, spectral
   classes and type of irregular variable stars of the trapezia components.
   In the notes identification of the main star and also the one of the
   trapezia components is given.
