The figure shows the nonlinearity curve of HyperLab's Nonlinearity module for the 152Eu lines of a calibration measurement.
The curve itself is depicted by a red line, its ±1σ limit with blue lines, while the data points are from the centroid shift of the fitted peaks.
The green triangles show the points where the curve reaches the zero nonlinearity value.
In HyperLab, the system nonlinearity curve always uses the channelchannel scale, as with these units the nonlinearity characteristics are supposed to be slowly varying with the time.
