Changes in the total reflected flux ΔF (panels a and c) and ΔP (panels b and d) during lunar transits at α = 67.2° (top panels) and planetary eclipses at α = 72.5° (bottom panels) for various lunar-to-planetary radius ratios r. The horizontal axis shows the elapsed time since the concentric alignment of the planet and moon as seen from the star in the case of an eclipse and as seen from the observer in the case of a transit. The time step of these simulations is 3 min. The baseline lunar-to-planetary radius ratio r is about 0.3.
