NB. (2) The annulas mirror, which used to be actuated to switch between acquistion and guiding mode, should '''NOT''' be actuated anymore for any reason. There is no danger in doing so but the new routines rely on the annuls mirror staying in the "SCIENCE" position (see Figure 3 below). There are plans to maybe disable the actuating motor eventually.
