Dear pwscf users, I have obtained Hubbard U values for Ta atoms in Ta2O5 system. The values are 1.9 eV and 2.8 eV for two not equivalent atoms. I am confused about such relevant difference in the the values. As I understand Hubbard U characterizes the sort of atom and its coordination should not influence on the value. Could you help me to figure out what is wrong?
Thank you in advance, Maxim
