# The omega2.out output file

This file contains the frequency square $\omega^2(\vec{k})$ at different k points.
• It has N_kpoints rows and 3 * N_basis columns, where  N_basis is the number of basis atoms in the unit cell define in the basis.in file and N_kpoints is the number of k points in the kpoints.in file.
• Each line corresponds to one k point. Each line has 3 * N_basis numbers, corresponding to
the 3 * N_basis values for $\omega^2(\vec{k})$ (in units of [THz]2) in the order of increasing magnitude.
