Appendix E: What is Full Width at Half Maximum (FWHM)
Full Width at Half Maximum (FWHM) is the full width of the distribution (in ATREM, Gaussian Distribution) at half of the maximum intensity.
Figure E1: A Gaussian profile with a Full Width at Half Maximum (FWHM) of 10 nm is shown. This profile is typical of spectrometers such as AVIRIS which has 224 such profiles spaced at about 10 nm (Clark, 1997).
