The axis of rotation of the switch mirror is aligned with the beam axis between F2CAL and F3CAL (the switch mirror). In this configuration, the switch mirror is set at the position angle 59.4 which corresponds to the reference beam pointing to SKY2.

This is the tricky one because the beam has to pass by F2CAL without truncation. It is for this reason that a bite has been machined out of F2CAL.
