Only groups of multiplicity >3 for muon threshold energies equal to 0.25; 0.85; 2.0 and 3.2 TeV were selected for the analysis. A distribution of the events on the alignment parameter /lambda has been obtained and compared with the results of Monte-Carlo simulation made for this experiment. Upper limit for aligned muon groups flux is given.4 pages, 2 figures, submitted to 29th ICRC, Pune, IndiaAstrophysicstext
