Light curves for a flare with parameters of Table 1 with B = 65 mG for two energy bands (left) and evolution of the simulated time delays between them as a function of time (right). The LIV-like delay overlaid for comparison has been obtained by simulating two asymmetric Gaussian light curves with an injected constant delay of Δt = 500 s. Only positive delays are shown here in logarithmic scale, which can be directly compared to the Lewis et al. (2016) description.
