Template maps tested to reproduce the GeV excess emission toward the LHAASO/H.E.S.S. source. (a) The H.E.S.S. intensity map. (b) The N_p map of Y. Su et al. (2017) velocity range (58.4–62.2 km s⁻¹). (c) The N_p map of H. Sano et al. (2018) velocity range (23.2–26.4 km s⁻¹). (d) The same as (c), but N_p in the annulus is scaled by 1/2.10 (see the text for details). There, the solid circle (with a radius of ﹩0\mathop{.}\limits^{^\circ }49﹩; the same as the yellow circle in Figure 1) shows the size of the spherical shell of HESS J1912+101 used in the initial modeling, and the dashed circle (with a radius of ﹩0\mathop{.}\limits^{^\circ }87﹩) shows the area used in the final modeling. The H.E.S.S. intensity map is arbitrarily scaled to be compatible with Fermitools. The unit of N_p maps is 10²¹ cm⁻².
