Fig. 3 The left plot (a) is for $\epsilon_1$ and the right plot (b) for $\epsilon_2$ with the Starobinsky potential of the form $V(\phi)=({3}/{4})M^2 \left(\phi -M_{\rm Pl} \right)^2$ with $M = 1.4286 \times 10^{-6}m_{\rm Pl}$ and $m_{\rm Pl}=1$ in the Jordan frame for KED case with $\dot{\phi_B}<0$.
