Dear users and developlers,

I'm doing phonon calculations and got the output of phonon mode eigenfrequencies and corresponding eigenvectors (eivec 1). From the output, I got list of eigenfrequencies and corresponding eigenvectors, however, I don't really understand the format of the following output for "Analysis of degeneracies and characters":

Symmetry characters of vibration mode #   1
       degenerate with vibration modes #   2 to    3
3.0 -3.0 1.0 -1.0 0.0 0.0 1.0 -1.0 0.0 0.0 1.0 -1.0
Symmetry characters of vibration mode #   4
        degenerate with vibration mode #   5
2.0 2.0 0.0 0.0 -1.0 -1.0 0.0 0.0 -1.0 -1.0 0.0 0.0
Symmetry characters of vibration mode #   6
1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0
Symmetry characters of vibration mode #   7
        degenerate with vibration mode #   8
2.0 -2.0 0.0 0.0 -1.0 1.0 0.0 0.0 -1.0 1.0 0.0 0.0

Could you please tell me what are the quantities those 12 columns for each mode correspond to ? Thanks a lot!

Sincerely,
Bo
