Thanks in deep Andrea and Lorenzo.
I completely missed that ...

Thanks Lorenzo, I am aware of the ghosts. That's the very first try, so
there is a lot of run for improvement.

Humm .. I wonder why.
Those ghosts are out of the interval of -2.5 to 0 Ry which one would
expect to be the important one for the bonding in this case. Besides the
log derivative is reproduced very well in that interval. So, all the
ground state properties calculated with that psp should be fine except,
perhaps, the band gap in systems with one. It should also work for metals
without any problems.

Bye, L.
