$\chi^2_{\rm reduced}$ $1.17\pm0.08$ $ 1.21\pm 0.03$
The reduced $\chi ^2$ were calculated with 414 degrees of freedom for CoRoT-3b and 2890 for HD 189773b.
Nota Bene: $\beta = -\lambda$; $\beta$ is used since the first reference of a projected spin-orbit angle was named thus, in Hosokawa (1953). $V~\sin(I)$s are probably overestimated, see Sect. 4 for details.
