DENSITY,orbc.filec, ODENSITY,orbo.fileo,
For non-self-consistent
DFT calculations, specifies the source of the density matrix.
The total density is read from orbc.filec, with further options
specifying density sets in the standard way as described in
Section 2.16.
ODENSITY can be used to specify the spin density.
The defaults are the densities last
written by an SCF or MCSCF program.
