The residual counts map above 10 GeV in the 5° × 5° region near W43, with pixel size of 0.1° × 0.1°, smoothed with a Gaussian filter of 0.2°. The color bars represent the counts per pixel. The white circle is the best-fit uniform disk template. The small black circle marks the position of the star forming region W43-main. The cyan diamonds are the weak sources S1 and S2. The green crosses indicate the point sources listed in the 4FGL. The magenta circle marks the position and size of the TeV source HESS J1848-018. The two black crosses mark the position of the two HESS point sources, HESS J1846-029 (left) and HESS J1844-030 (right), respectively. The white boxes are the positions of the nearby SNRs.
