In the light of the BICEP2 result $r \\approx 0.2$, all model parameters and relevant observables are computed. It is found the curvaton field value is constrained into a narrow range, $\\sigma_* = \\mathcal{O}(10^{-2}$-$10^{-1})$ and the running of the spectral index is $n_s' \\gtrsim -10^{-3}$. We show that if the curvaton is added, the models are heavily degenerated on the $n_s$ - $r$ plane. However, introducing a new plane, the degeneracy can be resolved.
