Post the introduction to the output file specfun_sup.phon?
Real Sigma(w)[meV] is the real part of phonon self-energy. But what's meaning of the Im Sigma(w=0)[meV] ? How to get the phonon frequency due to phonon self-energy?

#Phonon eigenenergies + real and im part of phonon self-energy (meV)
#Q-point Mode w_q[eV] w[eV] Real Sigma(w)[meV] Im Sigma(w=0)[meV] Im Sigma(w)[meV]
