 \caption{\label{table_ul}Flux upper limits at \cl\ confidence level for the pulsar position in~${\rm s}^{-1}~{\rm cm}^{-2}$. 
   The upper limits from Method~A were calculated assuming a photon index of $\Gamma = 2.5$. The numbers
   in parentheses are the energy thresholds (in TeV) for which the upper limits were \mbox{determined}. }
