LVTOT = [logical]
Default: LVTOT = .FALSE. 

Description: LVTOT determines whether the total local potential (in eV) is written to the LOCPOT file

where is the ionic potential, the second term is the Hartree potential and is the exchange-correlation potential.

If LVTOT=.TRUE., the sum of the ionic, Hartree, and exchange-correlation potential is written to the LOCPOT file. Please also read the section on the tag LVHAR for further information.
