WebJul 20, 2024 · The FWHM can then be calculated from the imaginary pixel surface formed by these pixels: surface:=pi *sqr ( r ). r:=sqrt (surface/pi) d:=2*sqrt (surface/pi) star_fwhm:=2*sqrt (pixel_counter/pi) where pixel_counter contains the pixels with a value above 0.5*peak. Personally I don't see a purpose for the FWHM once you have the … WebOct 11, 2016 · I typed a typical normal distribution, but you can also use Gauss etc. Your code looks pretty okay, except one thing: The guess values are for the parameters in the def fitFunc, i.e. the first value in guess is for x0 (the x-offset) and the second for the sigma (i.e. basically FWHM, with a few prefactors). What is your problem with the code?

In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y-axis which are half the maximum amplitude. Half width at half maximum (HWHM) is half of the FWH…
