 \caption{\label{tab3}Radius of a 22.6~$\mearth$ planet at 2~Gyr with different water core masses, EOS and levels of irradiation, characterised by a stellar incident flux, $F_{\rm inc}$. Two cases are considered: no irradiation ($F_{\rm inc}=0$)
and $F_{\rm inc}=6 \times F_{\rm inc}$ of GJ~436b. Comparison is done with the pure water (ice) case of Seager et~al. (\cite{Seager2007}).
Results based on the assumption of a uniform core temperature of $T=300$~K are also given.}
