Broadband nonthermal modeling of the SNR G150.3+4.5 in a leptonic scenario using a distance of d = 0.7 kpc (left) and d = 4.5 kpc (right). The radio fluxes, which are near lower limits (see Sect. 4.3), come from Gerbrandt et al. (2014) and the best-fit spectrum and γ-ray fluxes are those derived using the disk model. The ROSAT upper limit on the absorbed flux is derived in Sect. 3.2 and has to be compared to the absorbed X-ray synchrotron model (dashed blue curve). The values used for the plots are reported in Table 3.
