RooEffProd: 2-D efficiency modifying 2-D PDFS?

Is it possible to successfully use RooEffProd with a two-dimensional efficiency function to modify 2-dimensional PDFs? (I’m dealing with a two-dimensional camera acceptance that modulates a flat background and a gaussian signal distribution).

Hi Amanda,

Yes, that’s possible. In fact there is a tutorial macro that demonstrates it.
Here is a link.
