EMIN = real number (minimum energy for evaluation of DOS) EMAX = real number (maximum energy for evaluation of DOS) NEDOS= integer (number of grid points in DOS)defaults: EMIN and EMAX default to sensible values given by the minium and maximum band energies. NEDOS defaults to NEDOS= 300.
The first two tags determine the energy-range in eV, for which the DOS is calculated. VASP evaluates the DOS each NBLOCK steps and writes the DOS after NBLOCK*KBLOCK steps to the file DOSCAR. If you are not sure where the region of interest lies, set EMIN to a value larger than EMAX.
