[Wien] Directions in OPTIC program

[Dileep Krishnan]

Dear users and developers,

I am using OPTIC program in wien2k to calculate the optical properties in hexagonal system MoS2 where my lattice vectors are nonorthogonal. I get imaginary part of the dieclectric function as eps(xx), eps(yy), and eps(zz). I assume that the eps(xx) will be along the a lattice vector, yy and zz are orthogonal to it. Am I correct or are they along the 3 lattice vectors?
