Does it mean the calculated eloss_xx corrsponds to the experiment in which the incident electron are perpendicular to the x direction?

nope

conv angle is not taken into account (let's say it is zero then)

Hi dear colleague,

please see the following article (Moreau and Cheynet,Ultramicroscopy 94 
(2003) 293-303) and the references in it :),

not so easy to do a "real" comparison....

best regards

Philippe Moreau
