Moment of inertia as a function of the protomagnetar mass for 8 EOSs using 4 sGRB samples considering the magnetic dipole radiation and GW emission. The parameter of ellipticity is ε = 0.005, which is the same value in Gao et al. (2016). Like Fig. 3, the 4 sGRBs are represeted by different colors and the black dashed line represents the relation of moment of inertia and mass in the case of Kepler rotation. we also painted the situation of R = 13 km. The theoretical mass estimates are shown in Table 4.
