Detailed Description

Concrete class for alignment parameters and associated quantities [derived from AlignmentParameters]. The alignable is assumed to have in fact two surfaces devided at a specific local ySplit. The number of parameters N_PARAM is 2x9, i.e. one set of

• 3 translations
• 3 rotations/slopes
• 3 bows/sagittas (u, v and mixed term) for the two surfaces (similar as in BowedSurfaceAlignmentParameters). Storage is done differently: The movements and translations are averaged and applied to the alignable in the 'classical' way. In SurfaceDeformation we store:

the half differences of the movements and rotations, to be taken into account, with positive/negative sign, for corrections for the surface at lower/higher y,

• the mean values 'm' and half differences 'hd' of the bows/sagittas of each surface, where these corrections have to be applied as m+hd for the one and m-hd for the other sensor
