Modulations of pulsations by the eclipse computed in a hypothetical binary system. Both stars are spherical, the orbit is circular, the inclination is 85°, and the secondary radius is half of the primary radius. The left panel shows with blue lines the eclipse footprint of the secondary on the circular disc of the primary. Only the footprints corresponding to every fifth point of the light curves on the right panels are shown for clarity. The right panels show the actual light changes for two selected modes: (0,0) on top and (2,1) on bottom.
