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"?

WebNov 3, 2015 · The reason why i ask is that I did a quick lorentzian fit on my data and got this as an output: Coefficient values ± one standard deviation. y0 =1.0451 ± 0.544. A =94831 ± 1.19e+004. x0 =654.5 ± 1.97. B =1893.6 ± 278. So if B= (1/2 * FWHM)^2 then A=1/2 * FWHM. When i look at my peak have a FWHM at ~87 and an amplitude/height … WebFit ODE; Neural Network Fitting; Fit Convolution; Polynomial Surface fit; Enzyme Kinetics; Drug Dissolution Analysis; More...
