Top panel: spectral peak energies for inclinations of ﹩12\buildrel{\circ}\over{.} 5﹩ (solid line) and ﹩82\buildrel{\circ}\over{.} 5﹩ (dashed line) for all simulated caustic crossing angles and caustic offsets. Bottom panel: spectral peak energies as a function of inclination i (the box size is proportional to the number of simulated events). Both panels: ﹩a=0.5﹩, ﹩h=5\,{r}_{{\rm{g}}}﹩, ﹩\beta =0.5﹩.
