Radial velocity of HD 73344 resulting from the joint analysis of the photometric and RV data. Panel a: RV of SOPHIE (black) and HIRES (yellow) observations and best fitting model (purple). Panel b: RV residuals. Panel c: RV phased at the period of planet b (planet c and activity models subtracted). Panel d: RV phased at the period of planet c (planet b and activity models subtracted). Best-fitting models for planets b and c are shown in red.
