FWHM: FWHM and HWHM
In bgrich/JLstartup: Start-up Functions for Analysis

Description Usage Arguments Details

Returns the width of a given spectrum.

FWHM(spectrum)

HWHMleft(spectrum)

HWHMright(spectrum)

spectrum

a numeric matrix. The x and y coordinates of the function whose width is to be measured.

These functions provide the full-width at half-maximum or the half-width at half-maximum depending on the function. Given a two column matrix describing the x and y positions of a spectrum, the function finds the location of the maximum and finds the spot just below the half-max point on either side of the peak. The function approx is used to determine the actual location of the half-max point on either side of the maximum. The separation of these two points is then computed provided the full maximum. For the half-width functions, onlye the right side is computed in HWHMright and only the left side is computed in HWHMleft.
