Number of q points. Must be identical to that of the preceding ph.x run
with electron_phonon='ahc'.

ahc_nbndskip of the ph.x run with electron_phonon='ahc'.
         
 |  
| flvec | CHARACTER |  
| Status: | REQUIRED |  | 
File containing the normalized phonon displacements written by matdyn.x.
         
 |  
| eta | REAL |  
| Status: | REQUIRED |  | 
Magnitude of the small imaginary component included to smooth the energy
denominators, in Ry.
