[Wien] 3rd and 4th column of case.trace file generated by using Boltztrap code

[sonusharma at iitmandi.ac.in]

Dear all
I want to know about the 3rd and 4th column of case.trace file which is
calculated by using the BoltzTrap code. What are these N and DOS (Ef) and
what formula is used to calculate them. Is there any reference available
in which these N and DOS are calculated and formula is given to calculate
them.

Thanking You
