LREAL
LREAL = .TRUE. | .FALSE. | On (or O) | Auto (or A)
Default: LREAL = .FALSE.
Description: LREAL determines whether the projection operators are evaluated in real-space or in reciprocal space.
| LREAL=.FALSE. | projection done in reciprocal space |
| LREAL=.TRUE. | projection done in real space, (old, superseded by LREAL=O) |
| LREAL=On or O | projection done in real space, projection operators are re-optimized |
| LREAL=Auto or A | projection done in real space, fully automatic optimization of projection operators (no user interference required) |
