  2. aOur models are characterized by standard afterglow parameters: spectral index p (held fixed), circumburst density n, isotropic-equivalent blastwave energy Ek,iso, and shock microphysical parameters εe and εb. The structured jet model is further defined by the three angular parameters: the Gaussian width of the energy distribution θc, the viewing angle θv, and the wings truncation angle θw. The cocoon model is defined by the mass of relativistic ejecta Mej, their maximum umax and minimum umin velocity, and their energy profile with power law slope k
