Dear Experts,

I am trying to fit bs mass with double gaussian(signal) and gaussian+exponetial (background). The fit status shows good, but there is two bins(peak one around 5.36 and another around 5.31) which are not fitted properly. I am attaching the plot and code. Could you please tell me how to fit these two bins?

Thanks,
Deepak
