Phase-folded light curve of planets HD 93963 Ab (left panel), and c (right panel). Upper panels: photometric measurements are shown with light grey circles, along with the 10-minute binned data (green circles for TESS, and red for CHEOPS), and the best-fitting transit model (solid black line). On the right-hand side of the plot, we also show the size of TESS and CHEOPS error-bars, respectively in green and red. Lower panels: residuals, colour-coded as above.
