WebThe peak is "well-sampled", so that less than 10% of the area or volume under the peak (area if a 1D Gaussian, volume if a 2D Gaussian) lies outside the measurement region. The width of the peak is much larger than the distance between sample locations (i.e. the detector pixels must be at least 5 times smaller than the Gaussian FWHM). WebMar 24, 2024 · The full width at half maximum (FWHM) is a parameter commonly used to describe the width of a "bump" on a curve or function. It is given by the distance between …

WebThe theoretical area under these Gaussians is all the same: 1.0645* Height*Width = 1*3*1.0645= 3.1938. A perfect area-measuring algorithm would return this number for all five peaks. As the broadening is increased from left to right, the peak height decreases (by about 35%) and peak width increases (by about 32%).
