Simulated planet-moon observations (black points) with a noise amplitude of 100 ppm per data point and a 10 min cadence, roughly corresponding to an idealized observation of an m_v ~ 11 photometrically quiet Sun-like star in PLATO’s P5 sample. The system is the same as in Fig. 3 (see Sect. 3.2 for details), (a) Same transit as in Fig. 3d, but with a new realization of the random noise. From our Ul traNest recovery, we selected 100 model parameters from the posteriors and we show their light curves for the moon (orange), planet (blue), and total (gray) light curves.
