Dear Dr. Che R. Seabourne Hello. I contacted Prof. Kevin Jorissen, who is the main developer of TELNES, with Prof. Peter Blaha's help. The Euler angles (0,0,0) of "Orientation Sensitive" means that the electron beam is parallel to the c-axis of the crystal.
ORIENTATION SENSITIVE alpha beta gamma ? 1.rotate alpha degrees about z-axis 2.rotate beta degrees about y-axis 3.rotate gamma degrees about z-axis In addition, ORIENTATION SENSITIVE mode needs bigger values of NR and/or NT as far as I know. In my case, NR is 50.(30 was too small) Best wishes Y.
