Table 2: Results of the radial velocity curve fits. Left block: results from the inversion based $\chi ^2$ -minimization. Right block: results from the genetic algorithm optimization. The blocks give the best fit value and lower and higher limits. Note that the 3 $\sigma$ deviation of the pikaia fits are smaller than 1%.

**Table 2:** Results of the radial velocity curve fits. Left block: results from the inversion based $\chi ^2$ -minimization. Right block: results from the genetic algorithm optimization. The blocks give the best fit value and lower and higher limits. Note that the 3 $\sigma$ deviation of the `pikaia` fits are smaller than 1%.
