Illustration of our transit injection and retrieval experiment. Simulations include two transits of an Earth-sized planet with an orbital period of 364 d in a 2yr light curve of an m_V = 9 Sun-like star. (a) PLATO-like light curve generated with PSLS. The red line shows the trend computed with Wōtan. (b) Light curve after detrending with Wōtan. The simulated transits occur at about 91 d and 455 d (highlighted with green points), that is, near quarterly reorientations of the spacecraft. This example was deliberately chosen to illustrate that Woōtan and TLS can master non-well-behaved systems. (c) Phase-folded light curve of the transit detected with TLS. The best model fit is shown with a red line. The 21-bin walking median (ten data points symmetrically around each data point) is shown with a blue line.
