Three different simulated collision events with the relative velocity vectors pointed in three different directions, as shown in the upper right hand corner of the plot. On the y-axis we plot the luminosity L divided by the average luminosity over the duration of the light curve $\overline{L}$, and on the x-axis we plot time. We intentionally exclude units on the x-axis because the timescales over which the accretion events occur can vary widely, as shown in Fig. A.1. We see that while the overall magnitude of the event is not significantly affected by the relative velocity vector orientation, the shape of the light curve, including peaks, rises, and falls, is affected.
