Abstract
We present the first results of a program conducted to improve Salukvadze's Trapezium Multiple Systems Catalogue (TMSC). In order to accomplish our goal, we have cross-identified the data presented in the current edition of the TMSC (numbered I/134 in the Strasbourg's Data Center) with the Washington Double Stars Catalogue and 2MASS, among other large compilations. Variations in both position angles and separations have been detected for some systems.
