The Kramers-Kronig analysis is carried out for the actual number of
columns contained in the case.joint[up|dn] file. For each real
component its imaginary counterpart is created and vice versa. All
dielectric tensor components can be found in file
case.epsilon[up|dn]. The real and imaginary parts of the
optical conductivity (in 1015/s) are written to file
case.sigmak[up|dn]. In addition, file case.absorp
contains the real parts of the optical conductivity (in
and the absorption coefficients.
The output in case.epsilon[up|dn] and case.sigmak[up|dn] can be plotted with an xy-plotting package.
