This is a simple example project where I want to extract parameters from piece of spectrum data that I have. My gaussian function has the following form:

@@0@@

Where @@1@@ is a normalisation coefficient, @@2@@ is the center point, @@3@@ defines with the width of the curve and @@4@@ is the height above the x axis.

First lets load and plot the data

Clearly the data is a nice gaussian, so lets fit the function to get the center point and full-width at half max, which is given by

@@0@@

First we import some code which contains the gauss equation, and the optimize function from scipy to do the curve fitting.

So here we have a pretty good fit, and we were able to find the intensity, center point and width of the curve. Lets just finally calculate the FWHM
