Radial velocity curve of Gliese 86

The image shows the measurements (with error bars) of the radial velocity (V r vrs. orbital phase) of Gliese 86 with the new 1.2-m Swiss telescope and the CORALIE spectrograph at La Silla. They have been "phase-folded" with a period of 15.83 days and the diagramme thus represents one revolution of the planet around the star. The fully drawn line corresponds to the best orbital solution, obtained by least-square fitting a simple two-body model (star + planet) to the data. As can be seen, the agreement is near perfect and the dispersion of the measurements around this line is very small.
