Signals and spectra for the eclipses in an inclined system. The inclination angle is α = (s₁− s₂)∕r = s₁∕2r. This is the maximum value where complete eclipses always occur (case I). Same planet radii and axes as in Fig. 3. Top: observation direction is , along the line of nodes. Bottom: observation in direction . The eclipses are on the equator for ωt_k ≈ π. This is at the full phase and quarter phase, for top and bottom figures, respectively. Because there is a complete eclipse twice a month, there is little difference in the signals (see Fig. 5).
