Correlation plots of the recovered vs. model values for the magnetic field (a) and the viewing angle (b) for single power-law distribution of fast electrons over the kinetic energy. The red vertical bars represent the fitting ±1σ intervals around the recovered values, while the black horizontal bars represent the ±1σ intervals around the corresponding model parameters averaged along the line of sight associated with a given image pixel. Just for convenience, an ideal perfect correlation is indicated in each panel by a blue line. In panel (b), unlike in Figure  2(c), the ambiguity of the viewing angle recovery has been removed by using the "observational" data on the sense of polarization.
