Same as Fig. 4, but for the planet HD 233832 b. Literature Keck datapoints are shown in green and our HARPS-N data are plotted in red. Top panel: solid black curve shows the solution obtained setting a prior on orbital period centred on 2000 days, while the dashed curve is derived from an orbital prior centred around 4000 days. Middle and bottom panels: residuals from the 2000-day and 4000-day solutions, respectively.
