First of all, setrmt gives:
1 42.0 2.12 2.12
2 14.0 1.68 1.68
3 7.0 1.61 1.60
4 7.0 1.60 1.60
So the N radii are much larger and Si and Mo smaller.
It might be that the ghostband comes from N-2s, as the small RMT may not
allow for 2 radial functions. You could try to remove the LO for N-s
(only keep:
0.30 2 0 (GLOBAL E-PARAMETER WITH n OTHER CHOICES, global
APW/LAPW)
0 -1.07 0.0010 CONT 1
1 0.30 0.0000 CONT 1
for the N atoms (maybe use instead a HDLO).
