from the current to the sink. Five values are employed for the twist angle of form $\vec{\theta}=\left(\theta, 0, 0\right)$ and its permutations such that four-momentum transfer of the current takes the value $Q^2({\rm GeV}^2)=0.02, 0.04, 0.06, 0.08, 0.10$. Those values of $\theta$ are independent of $M_\pi$ as is easily checked for the momentum configuration chosen here. The fixed sink time $t_f$ is chosen to be 28, larger than that of data set I, for better suppression of excited states and also from examination of the dependence of the ratio on $t_f$. The fitting range is chosen symmetric around $t=14$ since the source is local after averaging over the $Z(2) \otimes Z(2)$ random numbers. We call this set of data as data set II. Statistics and results of data set II are tabulated in Table \[table:stat\_dataset2\] and Table \[table:PFF\_DataSet2\]. Results for $R'(\tau)$ for $M_\pi \approx 702$ MeV are plotted in Fig. \[fig:Plateau\_PFF\](b). One can see that the form factors of the data set II have much smaller error bars compared to those of data set I. We also plot results for the case of pion mass $M_\pi \approx 296 \rm MeV$ in Fig. \[fig:Plateau\_PFF\_296\](b).
