I have a custom signal PDF that I’m using to fit 5 angular distributions. This signal PDF is multiplied by a 5d efficiency PDF and then added to a 5d background PDF.
When plotting any of the 5 angles, it takes an extremely long time to perform the integrations needed to plot the PDFs on top of my dataset. In fact, plotting a single angle can take upwards of 4 hours…
Needless to say, this slows things down way too much since I’m having to fiddle with parameters and refit fairly often. I really can’t afford to wait an entire day to get my plots back…
Is there any way to decrease the number of integration steps when performing plotOn for a complex PDF?
