WebSep 27, 2024 · The FWHM algorithm (“FWHM/50% iso-intensity” section) was altered so that it returned the sub-pixel position of the FWxx, where the ‘xx’ is a user specified percentage of the signal intensity. The rationale behind this was; we know that the FW50 breaks down for small field sizes, but perhaps for each gap size width there is a different ... 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 … See more Normal distribution If the considered function is the density of a normal distribution of the form Other distributions In spectroscopy half the width at half maximum (here γ), … See more • Gaussian function • Cutoff frequency See more • FWHM at Wolfram Mathworld See more
