Webwidth at half height in seconds or minutes. This approach of using half-height peak width, also called full width at half maximum (FWHM), is especially useful with mass spectrometric detectors, which typically have more parameters that affect the data rate. By simply inputting the half-height WebSay your function peaks at y=10 at the point x = 2. You want the half max, so y=5. And you want the full width at half max, so you find the point to the right of x=2 where y=5, say at x=9, and the point to the left where y=5, say x=0. The full width of your signal at half its maximum value is 9-0 = 9.
