http://openafox.com/science/peak-function-derivations.html WebMay 5, 2024 · 1. I've plotted a dataset in SciDAVis and added the default Gaussian fit. SciDAVis used the following function: f ( x) = y 0 + A ⋅ 2 π w ⋅ exp ( − 2 ⋅ ( ( x − x c) w) 2) Where y 0 is the offset on the y axis, A is the amplitude, w the width and x c the position of the maximum on the x axis. All good, but what do they mean by "width"?
