Same as Fig. 4, but for HD 157338 B. Top left: radial-velocity orbit induced by HD 157338 B. The white data points show the HIRES data, the blue data points show the COR-98 data, the cyan data points show the HARPS data, the yellow points show the COR-07 data, and the green points show the COR-14 data. Top right: predicted past and future relative astrometric points are shown as black circles with their respective years, while the observed relative astrometric points from the 2006 VLT/NACO data and the 2021 VLT/SPHERE data are shown as blue filled data points, where the measurement error is smaller than the plotted symbol.
