I am using cp2k to calculate energy of COF systems. This system has occupied orbitals up to 229/230th state. If I add more than required MOS will it make much difference?this is my smear input-

&SMEAR ON

METHOD FERMI_DIRAC

ELECTRONIC_TEMPERATURE 298.15

&END SMEAR

and this is my scf part-

&SCF

SCF_GUESS RESTART

MAX_SCF 100

EPS_SCF 1.0E-6

ADDED_MOS 200
