Radial velocity curve of HD 47536

Radial velocity curve of HD 47536, caused by the pull of the orbiting planet during the 712-day period (abscissa: Julian Date - 2,400,000; ordinate: velocity in kilometres per second along the line-of-sight). Error bars indicate the accuracy of the measurements. The fully-drawn curve is the computed velocity curve, corresponding to the best-fitting planetary orbit. The lower part of the diagram displays the deviation of the measurements from this curve — in the mean about 0.025 km/sec, or 25 m/sec.
