Modeling of the SED of SNR G106.3+2.7. The left and right panels show the results of the head and the tail, respectively. The top and bottom panels show the results of the leptonic and hadronic models, respectively. The white circles show the radio flux of each region (Pineault & Joncas 2000). The black bow-tie area shows a power-law fit and 1σ statistical errors measured by Suzaku (Fujita et al. 2021). The open triangles show the Fermi-LAT measurements (Xin et al. 2019; Liu et al. 2020). The markers in the TeV γ-ray band are the same as in Fig. 4, but those corresponding to the MAGIC data are shown in black here. The red, blue and green lines show the hadronic, IC and synchrotron emission. The model parameters of each panel are summarized in Table 3. In the top-right panel, the solid and dashed lines show the leptonic emission with the energy cutoff of 120 and 1200 TeV, respectively.
