Fig. 4.

Left: gamma-ray differential energy spectrum of the northeastern MC (J1801-233). Fermi-LAT and HESS data have been fitted with a hadronic model (see Aharonian et al. 2008; Abdo et al. 2010, for references). Right: synchrotron emission spectrum observed from the entire SNR (Kovalenko et al. 1994; Dubner et al. 2000). A fit to data is shown as a dashed line. The maximum contribution from the northeastern cloud is also shown (see text for details).
