Top panel: AGILE (red) and Fermi-LAT (green) old spectral energy distribution (SED) of W44 (Giuliani et al. 2011; Abdo et al. 2010e), with the new Fermi-LAT (magenta, Ackermann et al. 2013). The new AGILE data are shown in blue in Fig. 1. Bottom panel: Fermi-LAT new (magenta, Ackermann et al. 2013) and old (green, Abdo et al. 2010e) spectral energy distributions. We note that there is a substantial difference at low-energies between the two data sets.
