WebJan 20, 2014 · In Excel, I have two columns X and Y, and Y is Gaussian type of peak, how can I find the Full-width half maximum (FWHM)? I want to find all Y cells that are greater than half maximum and find the first and last corresponding X values, how can I do that? Is there a better way? excel; WebFind the minimum and maximum points and calculate difference. difference = max (arr_y) - min (arr_y) Find the half max (in this case it is half min) HM = difference / 2. Find the nearest data point to HM: nearest = (np.abs (arr_y - HM)).argmin () Calculate the distance between nearest and min to get the HWHM, then mult by 2 to get the FWHM. Share.

WebThe term FWHM refers to the width of an optical signal at half its maximum intensity. This measure gives the bandwidth of a light source operating at 50% capacity. It is also an important property for determining color … WebA Lorentzian function is defined as: A π ( Γ 2 ( x − x 0) 2 + ( Γ 2) 2) where: A (Amplitude) - Intensity scaling. x 0 (PeakCentre) - centre of peak. Γ / 2 (HWHM) - half-width at half-maximum. Note that the FWHM (Full Width Half Maximum) equals two times HWHM, and the integral over the Lorentzian equals the intensity scaling A.
