The BSEFATBAND file contains the NBSEEIG number of eigenvectors of the BSE Hamiltonian.

The file has the following structure:

  rank of the BSE matrix                NBSEEIG
  1BSE eigenvalue    E_BSE      IP-eigenvalue:    E_IP
Kx Ky Kz E_h E_e Abs(X_BSE)/W_k NB_h NB_h Re(X_BSE)+ i*Im(X_BSE)   
...
  2BSE eigenvalue    E_BSE      IP-eigenvalue:    E_IP
Kx Ky Kz E_h E_e Abs(X_BSE)/W_k NB_h NB_h Re(X_BSE)+ i*Im(X_BSE)
...
   NBSEEIGBSE eigenvalue    E_BSE      IP-eigenvalue:    E_IP
Kx Ky Kz E_h E_e Abs(X_BSE)/W_k NB_h NB_h Re(X_BSE)+ i*Im(X_BSE)   

where E_BSE and E_IP are the BSE and IP transition energies, KX KY KZ the k-point coordinates, E_h and E_e the hole and electron eigenvalues, X_BSE the component of the eigenvector, W_k the weight of the k point, and NB_h NB_e the hole and electron orbital numbers.
