Excess counts sky maps of the Geminga region above 0.5 TeV using the 2019 dataset with two different background estimation methods. Left: On-Off background estimation method. Right: field-of-view background estimation method. The maps are over-sampled with a 0.08º correlation radius, with contours at the level of 50 and 100 excess counts from maps over-sampled with a 0.5° correlation radius. The 68% containment PSF is shown for comparison and has a value of 0.06º, valid for the innermost θ < 1° region around the pulsar in which the significance is evaluated (indicated by a dashed circle). The Galactic plane is indicated by a green dashed line and the pulsar location with a green triangle, whilst an arrow indicates the proper motion direction of the pulsar (arbitrary length). Background normalisation is performed using regions at θ > 3.2°, indicated by a dotted circle.
