[mcstas-users] collimator_radial McStas component

[Emmanuel FARHI]

Hi Danielle,

Yes there are two models that you may use. The Collimator_radial may be
used both in approximated and exact models. They should be equivalent in
results. The transmission parameter is the maximum value of the triangular
transmission within the Soller blades.
