SCC-PS signal sanity check (estimators of piston, tip, and tilt according to the amplitude of misalignment in piston, tip, and tilt). The size of the SCC reference hole is not suitable here for a proper measurement (γ = 20, this value is undersized for the speed pupil comprising 169 segments, i.e. requires a γ > 30, but it is used for AITs and initial control purposes).
