Phase-folded radial velocities for planets LTT 1445A b (top panel), c (second panel), and d (third panel). The red squares are HARPS data, the orange circles are ESPRESSO data, and the red circles are the ESPRESSO data binned in 10 bins. The blue lines indicate the best fit obtained with the combined photometric and radial velocity datasets. The two last panels show the residuals for HARPS observations (second to bottom panel) and ESPRESSO (bottom panel).
