[mcstas-users] roughness of mirror in the Guide component

[Kim Lefmann]

Dear Shu,

Most used versions of the Guides use a "flat" mirror, where the 
reflectivity curve is given by an analytical form or a tabulated input. I 
believe the roughness could be included in these tables (which we leave 
for the users to calculate).

There is a guide version, where waviness is included, i.e. where the 
deviations from a flat surface are much larger than the neutron 
wavelength. Here, the angle of exit does not equal the angle of incidence.

hope this helps.

best, Kim
