[QE-users] How to determine the ei(i) and x0(i)

Dear Imane, these option allow you to do a plot in the plane (aka 
rectangle) that has as four vertices

x0

x0+e1

x0+e2

x0+e1+e2

You have to choose it to be parallel to the surface and at a certain 
distance from it, depending on the STM characteristics. I guess there 
could be more information on how to choose this distance in the paper.
