Photon count map showing the 30 overlapping analysis regions, based on the 9Y-MST tiling scheme with additional fields added near the Galactic plane (10° < |b| < 20°). Each region overlaps adjacent fields by 2° to reduce edge effects during source detection. The inner Galactic plane (|b| ≤ 10°) is excluded from the analysis due to intense diffuse gamma-ray emission. DBSCAN clusters are denoted by blue circles
