SYNOPSIS

oct-casida_spectrum

[oct-casida_spectrum does not read standard input: all standard input will be simply ignored. An input file named inp must be present in the running directory. Also, oct-casida_spectrum accepts no command line arguments, since there is not a standard way to do this with Fortran 90.]

DESCRIPTION

This program is one of the octopus utilities.

It post-processes the files casida/casida, casida/petersilka and casida/eigenvalues, that contain the excitation energies of the system from a Casida run (CalculationMode = casida). Each pole is broadened into a Lorentzian peak.

The man pages of octopus and of the auxiliary octopus sub-programs (oct-something) are not intended to contain the documentation of the programs, but only their basic description. For where to find more documentation, see the "SEE ALSO" section below.
