valence XC contribution to KS orbitals without GW

[lwcamp]

When running a GW calculation, the code automatically generates and prints out the exchange-correlation contribution to the orbitals. Internally, it appears that the code generates an array vxc_val corresponding to the valence-only exchange correlation potential on the FFT grid used for the density and potential files, and uses this to generate the exchange-correlation contribution to the orbital eigenvalues. Is there a way to get abinit to either print out the exchange-correlation contribution for orbitals of interest or write the vxc_val array to a file without taking the time-consuming step of running a GW calculation?
