WebT2 strongly affects the width of a spectral peak. The line width of a peak is defined by its Full Width Half Maximum (FWHM) — the width of the peak measured at 50% of its maximum height. Spectral peaks are generally … WebThis Wikipedia article uses this definition of a Gaussian function: f ( x) = a exp ( − ( x − b) 2 2 c 2) and says that one way to define the width is to consider the full width at half maximum: FWHM = 2 2 ln 2 c ≈ 2.35482 c. In other words, the width of f ( x) is proportional to c. But, in my function ρ ( r), α appears in two places: in ...
