Applying a gaussian filter to a distribution

ROOT
#1

Hi. I have a TH1 histogram, and I’d like to “smear” it with a gaussian. Is there a simple way of doing this?

Thanks,

Areg

I think @moneta can help you.

Hi,

What exactly do you mean with smearing ? Modifying randomly the bin content by adding a normal variable ?
We on; t have a function for doing this in ROOT, but it its not difficult to do by looping on the bin content and modifying it.
If you need I can send you an example macro ?

Best Regards

Lorenzo
