RooAbsPdf - Disable Automatic Normalization For Parameters

Hi! I’ve written a Pdf which derives from RooAbsPdf (using the makePdf function in RooClassFactory). A big problem is that I have ~50 input variables but only three which should be normalized with respect to. If I let RooFit do the automatic normalization, it takes a prohibitively long time. Do you know what the best way to do the normalization only with respect to the three variables?

Is there a way to tell RooFit that these other parameters shouldn’t be considered when normalizing? Or do I need to implement the getAnalyticalIntegral and analyticalIntegral functions?

Thank you!
