Fit of the orbit of HIP70849. Top left: Fit of the HIP70849 RV measurements. Top right: Fit of the HIP70849 astrometric acceleration in right ascension (left) and declination (right). The black points correspond to the HIPPARCOS and Gaia EDR3 proper motion measurements. In each plot, the black curve corresponds to the best fit. The color bar indicates the log-likelihood corresponding to the different fits plotted. Bottom: Corner plot of the fitted parameters of HIP70849 b. V0 and V1 correspond to H03 and H15, respectively.
