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 $1/(\Omega cm)$and the absorption coefficients.

The output in case.epsilon[up|dn] and case.sigmak[up|dn] can be plotted with an xy-plotting package.
