The old implementation had a side effect on option "e" that worked only when the "e" was the first character in the option string. This had a dramatic effect in tqo queries like J->Draw("etajet[1]","W*(Etjet[1]>70)","e1"); J->Draw("etajet[1]","W*(Etjet[1]>70)","Same,e1"); The second Draw was showing error bars different between tyhe first and second plot! git-svn-id: http://root.cern.ch/svn/root/trunk@8348 27541ba8-7e3a-0410-8455-c3a389f83636

// -- CLASS DESCRIPTION [REAL] --
//
// Implementation of BlindTools' CP asymmetry blinding method
// A RooUnblindCPAsymVar object is a real valued function
// object, constructed from a blind value holder and a
// set of unblinding parameters. 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
