findFWHM
Return to directory of Todd's CASA extensions
Measures the FWHM of the specified (y vs. x) profile by removing half the maximum (or other
specified fractional level) and using a spline fit to find the zero crossings. This works best
on noise-free data. To operate on images instead, see
getfwhm and
getfwhm2.
Usage:
au.findFWHM(x, y, level=0.5, s=0)
Example:
CASA <17>: au.findFWHM(range(-4,5,1),[0.1,0.15,0.3,0.7,0.95,0.8,0.4,0.3,0.2])
Out[17]: 3.3083849908301022
