sic oep</TT> With this option the optimized effective potential is
built in each step of the self-consistent process. Because the electrostatic
potential generated for each orbital involves a numerical
integration, this method can be expensive.

This option is similar to the oep option with the
addition of localization of the Kohn-Sham orbitals in each step of the 
self-consistent process.
