I need to draw Gaussian for each point separately and need to check their overlap area for comparison.

Since these two the distance between these two curves is 5 ppm (when compared with x - axis values). I would like to draw the Gaussian curves on ppm scale as base line.

I need to solve this problem. How can I calculate "meu" and sigma for such kind of comparisons and what is the exact formula which gives the distance between these two 2D graphs
