Dear cp2k users.

I am studying a system which consists of a Yb(III) doped YAG crystal. In 
particular I am analyzing the situation in which a Yb(III) cation replaces 
an octahedral Al(III).

I want to test pseudopotentials and norm-conserving 4f-in-Core base sets 
optimized for trivalent lanthanides.

Unfortunately I have the following error message in the output:

WARNING: Core states irregular for atom type Yb
WARNING: Redefine ELEC_CONF in the KIND section

Can anyone explain this error message to me?

I set the ELEC_CONF 3 6 2 0 keyword in the Kind of Yb atom section, but 
nothing changes.

In fact this is the pseudopotential I used:
Yb GTH-PBE-q11
   3 6 2 0
   0.56992615046703 2 17.21218420574061 -2.98206761055576
   3

   -3.33514928009212

The electronic configuration of Yb(III) is [Xe] 4f^13 6s^0.

I guess that's the correct electron configuration I should set up with this 
kind of pseudopotential, but I don't know how to do it

Thank you all

Alberto
