High-energy TS-maps 3500 GeV with 20 × 20 grid 0.05°/pixel, integrating over 7 yr of data. In both maps the 2WHSP J093430.1-172120 position is highlighted by a thick green circle centered on +; the 3FGL J0935.1-1736 is in the center of the thick cyan circle, and a blazar candidate (possible counterpart for the 3FGL source) is indicated with a thick magenta circle. Left panel: for this map, the 3FGL source is removed from the model input, showing the pure shape of TS distribution in the region. Green dashed line represents the 99% containment region for the γ-ray signature, which is compatible both with 3FGL and blazar candidate positions. The thin contour lines refer to TS surfaces of 40-30-20, only to show how the γ-ray signature is extended, matching the 2WHSP J093430.1-172120. Right panel: residual TS map (built using the 3FGL in the background) showing excess signal consistent with a point-like source. The green dashed lines correspond to the 68%, 95%, and 99% containment region for the γ-ray signature (from inner to outer lines).
