The max deviation (non linearity ) of a system

[Hayool]

Hi,

I have a question from my germanium lab, which is how to estimate the max deviation (non linearity ) of a system.
I plot the relation between the deviation of the energy as a function of true energy and got this ( see pic), but didn't know what to do next.

Thanks.

How is "maximal deviation" defined?

I moved the thread to the homework section.

The highest deviation which in the plot is (1400,610)
As i understood from one of my partners he used a linear line through the highest point and another line through the lowest one, then he found the difference between these two equations.
which i didn't know how to do.

Well, the data points look quite linear, so you can describe your data well. Then you look for some deviations, but with an unknown way to quantify those.
