Output file for variational parameters (***_opt.dat)

The average and deviation values of variational parameters and the energy optimized by the SR method are outputted in the following order:

\[\langle H \rangle, \langle H^2 \rangle, g_i, v_{ij}, \alpha_{2nt}^{d(h)}, \alpha_{4nt}^{d(h)}, f_{ij} \nonumber.\]

The type of average values is a complex number, while that of the deviation is a real number. Since the initial values of all variational parameters are specified at the beginning of the calculation, the calculation of physical quantities is done by using this file file. Here, *** is the header indicated by CParaFileHead in ModPara file.
