LHAASO J2226+6057 MWL SEDs along with the calculated model flux (top row), present lepton spectrum (middle row) and magnetic field evolution with time (bottom row) are given for t_age = 1000 yr (left column), 4000 yr (middle column) and 7000 yr (right column), for a fixed braking index n = 2.5. The radio data (green) and X-ray data (royalblue) are taken from Pineault & Joncas (2000) and Fujita et al. (2021) respectively. Fermi-LAT (brown), VERITAS (teal), Tibet ASγ (turquoise), MILAGRO (orange) and LHAASO (crimson) data are taken from Xin et al. (2019), Acciari et al. (2009), Tibet ASgamma Collaboration (2021), Abdo et al. (2009b) and Cao et al. (2021), respectively.
