Best-fitting model in comparison to the data. The upper plot shows the synchrotron and inverse Compton (IC) radiation by radio (R) and wind (W) electrons produced in the spatially varying magnetic field and seed photon field (blue and magenta coloured broken lines indicate the contributions from IC scattering on individual seed photon fields). The blue data points are used in the fit to determine the parameters listed in Table 4. The VHE data have been scaled using the values of ζ_i determined for each data-set (see text for further details) to adjust the energy scale for prediction given by the global minimum . In the lower plot, the relative residuals are shown (statistical uncertainties only).
