Guassian Function in Terms of FWHM #2

Closed ezbc closed 8 years ago

ezbc commented 8 years ago

In section 3.1.1 we need to confirm the Gaussian function description in terms of FWHM.

See the Wolfram description: http://mathworld.wolfram.com/GaussianFunction.html

I still think there's a problem with the equation in the python code. If you use

FWHM = 2.355 sigma

then the function gaussian returns

exp(-(x - mean)^2 / 4. / sigma^2)

which has a FWHM of sqrt(2) * 2.355 sigma (contradiction).

If you replace the 4 in the first divition by 2 you get exactly what I have in the equation in the document
