Multiwavelength SED from G288.8–6.3. The blue points are radio-flux measurements from Filipović et al. (2023), and the green points are the Fermi-LAT data points representing model 2 (left) and model 3 (right). The curves represent the best-fit Naima models with the particle population parameters indicated in Table 3. The solid curves represent the synchrotron emission, the dashed curves the inverse-Compton emission, and the dotted curves the Pion-decay emission.
