FERDO = [real array] 

Description: FERDO sets the occupancies of the states in the down-spin channel for ISMEAR=-2 and ISPIN=2.


To set the occupancies, specify

 FERDO = f(1) f(2) f(3) ... f(NBANDS×Nk)

The occupancies must be specified for all bands and k-points. The band-index runs fastest. The occupancies must be between 0 and 1.

The occupancies of the states in the spin-up channel must be specified by means of the FERWE-tag.
