When I use image analyzer add-in to convert the spectral result picture to data table.

Because the spectral line is too thick that it always with several Ys on the same X 。
Is there any way to get more accuracy Y from those data?
I draw a normal distribution line as an example, as you can see below, the line pass through X=330 with several Ys, and I use the B parameter as color variable to show B value of each location.
I try take Y as mean of Y, median Y, set B as weight of Y, but still can't get good enough result.
My goal is making the bias (or residual) lower than 0.0025, since the spectral need more accuracy result.
Below is my result so far, the bigger bias around 0.004, I also attached the data for reference.
