I am trying to do a 2D fit of below two distributions
using a delta function convoluted with the Double gaussian.
Here’s the complete folder that I am using : 2D_fit.zip (236.5 KB) but it’s not working.
Can you help me with this?
The convolution you want to do is possible in general. The problem in your code seems to me that you defined the Gaussian for
x=pi0_ErrM and the resolution model and convolution for
If you want to a convolution, you got to define the inputs for the same x axis. Maybe you meant to use
pi0_ErrM for everything up to the convolution? And then
pi0_M_prefit only for the RooJohnson in the other dimension?
Let me know if this goes in the right direction and if you have further questions!
Thank you very much. Now the code is working.
