the class RooUnblindPrecision has the following constructor:

RooUnblindPrecision::RooUnblindPrecision(const char *name, const char *title, const char *blindString, Double_t centralValue, Double_t scale, RooAbsReal& value, Bool_t sin2betaMode)
I’m wondering what are the parameters ‘centralValue’ and ‘scale’ doing. I tried a couple of values, but still I don’t have any clue what these parameters are changing. Documentation is unfortunately a bit rare… Would be nice I somebody could help me here.

Best wishes, Peter
