When supplied to a PDF // in lieu of a regular parameter, the blind value holder // supplied to the unblinder objects will in a fit be minimized // to blind value corresponding to the actual minimum of the // parameter. The transformation is chosen such that the // the error on the blind parameters is indentical to that // of the unblind parameter #include "RooFit.h" #include "RooArgSet.h" #include "RooArgSet.h" #include "RooUnblindUniform.h" ClassImp(RooUnblindUniform) ; RooUnblindUniform::RooUnblindUniform() : _blindEngine("") { // Default constructor } RooUnblindUniform::RooUnblindUniform(const char *name, const char *title, const char *blindString, Double_t scale, RooAbsReal& cpasym) : RooAbsHiddenReal(name,title), _value("value","Uniform blinded value",this,cpasym), _blindEngine(blindString,RooBlindTools::full,0.,scale) { // Constructor from a given RooAbsReal (to hold the blind value) and a set of blinding parameters } RooUnblindUniform::RooUnblindUniform(const RooUnblindUniform& other, const char* name) : RooAbsHiddenReal(other, name), _value("asym",this,other._value), _blindEngine(other._blindEngine) { // Copy constructor } RooUnblindUniform::~RooUnblindUniform() { // Destructor } Double_t RooUnblindUniform::evaluate() const { // Evaluate RooBlindTools unhide-offset method on blind value return _blindEngine.UnHideUniform(_value); }
