1–500 GeV significance maps for the region of GRS 1915+105–LHAASO. All sources in the best source model (4FGL J1916.3 (EXT) + GRS 1915+105–LHAASO (EXT = 0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩478)), except GRS 1915+105–LHAASO (EXT = 0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩478), were removed from the left panel of the map. GRS 1915+105–LHAASO (EXT 0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩478) was further removed in the right panel. The green pluses mark the positions of the Fermi catalog sources, the gray cross marks the position of GRS 1915+105, the cyan cross marks the center position of GRS 1915+105–LHAASO, and the cyan dashed and dotted circles mark the extension of GRS 1915+105–LHAASO derived from LHAASO observation (0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩267) and our spatial distribution analysis (0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩478), respectively.
