 ### BackgroundPdf: public ParamValues
-* **Private members:**
+Contains thhe constrained parameters, the pdf of the constrained paramerers, bool AtLeastOneConstrainFound, the RooFit funtions of (exponential, second exponential, ExpGaus function, Double Crystal ball) and the final background model pdf.
