Figure 1 shows a graph of brightness versus time for a star with three orbiting planets. The measurements were taken over a 40-day time period.
Figure 2 shows the light curves during the three individual planet transits: Planet Blue, Planet Purple, and Planet Red. On the x-axis, the “0” represents the midpoint of the transit.
