Dimensionless spectral shape for synchrotron emission, F(ν/ν_c) (see Eq. (8)) as a function of relativistic electron number density at orbital phase, φ = 0.8. This set of plots corresponds to a point close to the stagnation point (point “A” in Fig. 9) with ζ_rel = 0.15, ζ_B = 5 × 10^-5, and p = 1.6. Results are shown for frequencies, ν = 1.6, 5, 8, and 15 GHz. Corresponding electron distributions and emissivities are shown in the left column of Fig. 10; for this calculation, values to the left correspond to higher γ, and those to the right correspond to lower γ.
