[neutron-mc] McStas Polarisation details

[Dalgliesh, RM (Robert)]

Dear Peter and Emmanuel,
I've succesfully implemented polarising supermirrors, channeled guides and detectors using mcstas-1.8 over the past few days in a simple way but am now reaching the more technical details. I can rotate a component such as a single mirror through 90° but for the polarisation part of the calculation of the reflectivity the mirror needs to know what direction it is pointing in. The method of rotating the coordinate frame of the mirror doesn't allow me to know where things are pointing. Is there a way within mcstas to access the rotation matrix that has been applied to a component within that component.

Best regards

Rob
