WebThe half-intensity width (HIW) (or more precisely the Full-width at half-maximum (FWHM)) of a curved function is the distance between the points where the intensity is half of the maximum one. The HIW of a Point Spread Function is a good estimation of the device Spatial Resolution. It can be measured within the Twin Slicer by drawing a line ... Weband 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 the exponential and as a coefficient of the exponential. How should I define the width of ρ ( r)? algebra-precalculus
