May be relative energies are fine within the code itself. But what happens,
if different parts of the code are using different constants, might be
serious (to what level, I am not sure).  For example, EPW code in
qe-distribution defines bohr radius = 0.52917721092d0 (applicable to other
constants as well) different from that in PW.

with kind regards,
