Figure2c.m is the MATLAB script to plot Figure 2c in the paper.
critical2loop_couplings.dat contains the data for critical couplings obtained within 2-loop scheme: the first column is the spatial dimension $d$, the second column is the critical coupling $g^{I}$, and the third column is the critical coupling $g^{II}$.
critical3loop_couplings.dat contains the data for critical couplings obtained within 3-loop Borel resummation scheme: the first column is the spatial dimension $d$, the second column is the critical coupling $g^{I}$, and the third column is the critical coupling $g^{II}$.
