Residual flux in ppm assuming a sinusoidal shape of the phase curve for CHEOPS visits 1 to 15. The number in each panel corresponds to the CHEOPS visit, where the subscript a) refers to the residuals vs. BJD time-2450000 in the x-axis. The subscript b) refers to the density distribution, with density in the x-axis and residuals in the y-axis. All panels share the same y-axis scale.
