First, we fit the $\\gamma$-ray spectrum with a two-component photon model, namely synchrotron+blackbody, and then fit the recovered evolution of the synchrotron $\\nu F_{\\nu}$ peak to an analytic model derived considering the emission of a relativistic blast-wave expanding into an external medium. The prediction of the model for the $\\nu F_{\\nu}$ peak evolution matches well with the observations. We observe the blast-wave transitioning into ","authors_text":"A.
