Distribution of the square angular distance between the source position and the reconstructed gamma-ray origin (θ²) for low intensity (80–200 p.e.) excess events. A good agreement is seen between data from Crab Nebula observations and expectations from MC simulation with the likelihood reconstruction. The same distribution for the standard reconstruction (from Abe et al. 2023) is also displayed. Vertical lines represent the 68% containment for both data distributions and show that the likelihood reconstruction reaches a better angular resolution.
