gauss.hermite: Function to compute the Gauss-Hermite series up to order 4

In oczoske/slacR: R-package to measure v and sigma from VIMOS IFU cubes

Description

This function returns the Gauss-Hermite series as defined by van der Marel & Franx (1993) up to order 4.

Usage

gauss.hermite(x, x0, sigma, h3, h4, norm = TRUE)

Arguments

x	numeric vector
x0	mean of the Gaussian part of the Gauss-Hermite series
sigma	sigma of the Gaussian part of the Gauss-Hermite series
h3, h4	coefficients of the Hermite polynomials H.3 and H.4
norm	logical; if TRUE (default), the Gauss-Hermite series is normalized to unity

Details

The definition of the Gauss-Hermite series is that of van der Marel & Franx (1993) and might differ somewhat from other definitions.

Value

A numeric vector giving the values of the Gauss-Hermite series at x.
