Table 1: Analysis results: $N_{\rm on}$ and $N_{\rm off}$ are the event numbers in the ON and OFF regions, $\alpha$ is the normalisation factor. The results are reported for the standard $\theta ^2$ cut (column labelled Standard), for the cuts reproducing the conditions of the CANGAROO detection (column CANGAROO) and for the analysis of the radio arc (column Radio arc).

**Table 1:** Analysis results: $N_{\rm on}$ and $N_{\rm off}$ are the event numbers in the ON and OFF regions, $\alpha$ is the normalisation factor. The results are reported for the standard $\theta ^2$ cut (column labelled *Standard*), for the cuts reproducing the conditions of the CANGAROO detection (column *CANGAROO*) and for the analysis of the radio arc (column *Radio arc*).
