Table 5:

Statistical comparison of synthetic populations calculated with different type I migration efficiency factors $\f1$ .

All other parameters are kept constant, except that for the $\f1=1.0$ the seed mass is 0.1 instead of 0.6 $M_{\oplus }$ . The quantities are the same as in Table 1 and 3. Where possible, observational constraints are also given (Naef et al. 2005; FV05).
