/// \class TwoBowedSurfacesAlignmentParameters
///
/// 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
///
