SED of 4FGL J1912.7+0957 (red data) extracted from the H₂ spatial model. Statistical and systematic errors are considered. The blue data points are derived from the 4FGL J1913.3+1019 at the best two positions, as shown in Fig. 2. The black data points represent the HESS energy flux spectra taken from HESS J1912+101, and the green butterfly shows the best-fit power-law model with Γ = 2.64 ± 0.06 of 2HWC J1912+099.
