From top to bottom: phase-folded light curve of WASP-33 presented as black points showing the primary transit around phases 0,1 and the residual pulsations of the host star; relative flux of WASP-33 in parts per million (ppm) after removing the primary TM (second panel), the EV (third panel), and the DB (fourth panel). Last two panels: data binned at ϕ = 0.01 with the secondary eclipse plus phase curve at the top, and residuals from the best-fit model at the bottom. Red lines always showthe different components of the best-fit model.
