One- and two-dimensional projections of the posterior probability density distributions of the parameters for the radiative model of the X-ray and gamma-ray spectrum of the Vela X cocoon for Pointing 0. The parameters of the electron spectrum are defined in Eq. (3), and B is the strength of the magnetic field. The lines overlaid on the one-dimensional projections are the 16th, 50th and 84th percentiles of the distributions. The contours overlaid to the two-dimensional projections correspond to 1σ, 2σ, 3σ, and 4σ probability decrease with respect to the maximum.
