Figure 1. The absolute contributions of the vacuum condensates of dimension n for central values dependent on the energy scale $\mu =\sqrt{{M}_{P}^{2}-{{\mathbb{M}}}_{c}^{2}}$, where (I) and (II) denote ${susc}{\bar{u}}_{1}$ and ${susc}{\bar{u}}_{2}$, respectively, (a) and (b) correspond to ${J}^{P}={\tfrac{1}{2}}^{-}$ and ${\tfrac{1}{2}}^{+}$, respectively.
