Area under gaussian peak without exponential background

Hello, I need to find the area under a gaussian peak. The problem is that the data I’m fitting has an exponential background that I don’t want to consider. Is there a way of calculating just the integral of the area without the exponential?

I attached my code and also a set of data (it should be converted back to .CSV)

I do not understand the question. There is an analytical solution, you can certainly do this starting from the fitted parameter values.
Please correct me if I miss something.
