<p>Dear Andrey</p>
<p>q in turbo EELS code is given in cartesian coordinates in
2pi/alat units. For you case it means that you should always use
q_z = 0 and q_x, q_y you chose depending on what direction you
want to explore. For instance for Gamma-M in ibrav=4 (hexagonal
lattice) you vary q along q_y keeping both q_x and q_z = 0. <br>
</p>
<p>HTH</p>
