\caption{Parameters of the binary orbit for the star HD~100215.
Because we have too scarce data, the eccentricity has been arbitrarily
set to zero.
Consequently, the longitude of the periastron is not given.
The final rms of the residuals is 1.35~\kms.
Note that we have only used here the velocities computed from a Gaussian fit.}
