20Implementation of BlindTools' precision blinding method
21A RooUnblindPrecision object is a real valued function
22object, constructed from a blind value holder and a
23set of unblinding parameters. When supplied to a PDF
24in lieu of a regular parameter, the blind value holder
25supplied to the unblinded objects will in a fit be minimized
26to blind value corresponding to the actual minimum of the
27parameter. The transformation is chosen such that the
28the error on the blind parameters is identical to that
29of the unblind parameter
