order of moving and rotating

First of all a happy new year to all of you!

Now the question:
I'm trying to optimize the angle of a specific mirror in the neutron
path. From the manual and also the results of the calculations it is not
quite clear to me, how the mirror is moved and rotated and what the
reference points are.

Am I right, that any rotation is done after the translation, and that
the rotation axes are the (not translated) axes of the coordinate system
defined by the RELATIVE command? Or are only the directions of the
rotation axis those of the component defined by RELATIVE, but the center
of rotation now lies at (0,0,0) of the already moved component?
Thanks for any advice!
