<p class="MsoNormal">Hi Peter, Erik,<o:p></o:p></p>
<p class="MsoNormal">I’ve been looking in more detail at what happens when I rotate a polarising mirror or v-mirror in mcstas as a result of getting repeated assert errors from the polarisation being greater than 1.<o:p></o:p></p>
<p class="MsoNormal">I am having trouble working out if the polarisation vector is rotated correctly if e.g. Pol_mirror is rotated by 90deg to be in a horizontal rather than vertical geometry. The code performs a calculation of probabilities based on the sy
component (GetMonoPolRefProb(FN, FM, sy, &refWeight)) but if I have a polarisation in the x-z plane prior to the component I have been unable to determine what is happening.<o:p></o:p></p>
<p class="MsoNormal">In order to makes things correct the incoming spin vector would need to be rotated by 90 degrees on entering the pol_mirror component. Is this done in some hidden way or do I need to rewrite the components to deal with this?<o:p></o:p></p>
