Energy dependence of the synthetic synchrotron pulse profile with the photon frequency, ν normalized to ν₀, for a Vela-like solution (χ = 60°, α = 110°). Top panel: Light curves equally spaced in log ν/ν₀ from the lowest frequencies (bottom) to the highest frequencies (top). The bottom panel shows the full phase-frequency emission map. In both panels, light curves are normalized to the maximum flux for each frequency band. This figure only shows the contribution from positrons.
