WebIn spectroscopy half the width at half maximum (here γ ), HWHM, is in common use. For example, a Lorentzian/Cauchy distribution of height 1 πγ can be defined by Another important distribution function, related to solitons in optics, is the hyperbolic secant : Any translating element was omitted, since it does not affect the FWHM. WebThese three measurements are Equivalent Width, Full Width Half Maximum (FWHM), and Line-to-Continuum Flux Ratio. Shown in the figure above is the equivalent width (W) of an absorption line. The idea is you take the total area inside the absorption line, and create a rectangular box of the same area, extending from the continuum to the 0 flux line.
