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_v E_c Abs(X_BSE)/W_k NB_v NB_c Re(X_BSE)+ i*Im(X_BSE) ... 2BSE eigenvalue E_BSE IP-eigenvalue: E_IP Kx Ky Kz E_v E_c Abs(X_BSE)/W_k NB_v NB_c Re(X_BSE)+ i*Im(X_BSE) ... NBSEEIGBSE eigenvalue E_BSE IP-eigenvalue: E_IP Kx Ky Kz E_v E_c Abs(X_BSE)/W_k NB_v NB_c 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_v and E_c the eigenvalues of the valence and conduction band, respectively, X_BSE the component of the eigenvector, W_k the weight of the k point, and NB_v NB_c the valence and conduction orbital numbers.
