Hello, i have a optical signal(x is length in pixels and y is amplitude ) and i have found a number of FWHM values of peaks. The width is measured in pixels, let's say the average width of 50 peaks is 8,7 pixels, standard deviation is 0,6 and the average amplitude of peaks is 38 and standard deviation is 1,2. I want to find what's the error for the average value if i say that accuracy is 1 pixel. I want to plot a graph with all the peaks, average value and to show if deviations may be caused by observational errors or something else. I think that my attempt to find it is too simple. I just take 1/8,7 and find that the error is 11,5%.
