[Wien] why we need to divide plasma frequency by root(2)?

[Gavin Abo]

I could be wrong, but I think you just need to take the sqrt(2) of each 
plasma frequency:

2.074/sqrt(2) 2.074/sqrt(2) 1.264/sqrt(2)

then put them in case.inkram (not case.injoint).

You should be able to use multiple plasma frequencies in case.inkram but 
don't forget to add a Gamma for drude value for each of the plasma 
frequencies [
