emissiongaussian

Synopsis

A Gaussian model of an emission feature.

Description

A Gaussian model of an emission feature, where:

sigma = pos * fwhm / c / 2.354820044 delta = (x - pos) / sigma

if skew = 1,

f(x) = flux * exp (- delta**2 / 2) / sigma / 2.50662828

and, if skew != 1 and x <= pos,

f(x) = 2 * flux * exp(- delta**2 /2)/ sigma /2.50662828/(1+skew)

and, if skew != 1 and x > pos,

f(x) = 2 * flux * exp(- delta**2 /2/ skew**2)/ sigma /2.50662828/(1+skew)
