.INDENT 3.5
Second order perturbative correction to the wave function contained
in the \fI\%EZFIO\fP directory.
.sp
This programs runs the stochastic PT2 correction on all
\fBdeterminants n_states\fP wave functions stored in the \fI\%EZFIO\fP
directory.
.sp
The main option for the PT2 correction is the
\fBperturbation pt2_relative_error\fP which is the relative
stochastic error on the PT2 to reach before stopping the
sampling.
