Detailed Description

The BoundaryCheck class allows to steer the way surface boundaries are used for inside/outside checks of parameters.

These checks are performed in the local 2D frame of the surface and can either be:

• inside/outside with and without tolerance

• inside/outside according to a given chi2 value

  It also provides all the necessary tools for the individual implementations in the different SurfaceBounds classes.
