[CPMD-list] localized orbitals: Method?

[C. Klein]

Hello, 

among the many nice features of CPMD, there is the "LOCALIZE" function
which allows the localization of orbitals. I am just about to try this;
However, various localization methods have been described in the
literature, e.g. Pipek-Mezey, Edmiston-Ruedenberg, etc.. 

Now the question: Which one of those methods is used in cpmd? I would
like to give the proper credits (citation) to the method developers.

with best regards,
