No evidence for the pulsed emissions was found in our analysis. Upper limits at different energies were calculated for a $3 σ$ confidence level in the energy range of multi-TeV to several hundred TeV.4 pages, 3 figures, proceedings of 30th ICRC, International Cosmic Ray Conference 2007, Merida, Yucatan, Mexico, 3-11 July 2007Astrophysicstext
