Fig. 1


Distribution of squared angular distance, θ2, between the reconstructed arrival directions of γ-ray candidate events and the position of PSR 0205+6449 (red points). The distribution of θ2 for the OFF positions is also shown (gray filled histogram). The vertical dashed line defines the signal region ( deg2), Non is the number of events in the source region, Noff is the number of background events, estimated from the background regions and Nex = Non-Noff is the number of excess events.
