CHEOPS LC of WASP-3 and our best-fit model for the transits and eclipses. Upper-left panel: observed transit LCs (in cyan) offset vertically by multiples of 0.01 units. The dark blue points are the data points binned over 0.01 phase units. The full model, which includes instrumental trends, is shown in brown, and the transit model without trends is shown in green. Lower-left panel: residuals from the best-fit model to the transit LCs offset vertically by multiples of 0.005 units. Upper-right panel: Secondary eclipse LCs after removal of instrumental noise from our best-fit model, plotted without any vertical offset. Lower-right panel: residuals from the best-fit model to the secondary eclipses offset vertically by multiples of 0.005 units.
