HESE events with deposited energy above 100 TeV in Galactic coordinates (circles: showers, triangles: tracks). The purple contours represent intervals of declinations separated by 30^°, whereas the brown lines denote the Galactic latitudes b = 15^° and b = −15^°. Taking into account that the average angular resolution of shower-like events is ~ 15^°, we note an accumulation of events close to the Galactic plane, i.e., within the brown curves.
