Description

This function computes the first and second velocity moments of a Gauss-Hermite series given by the parameters x0, sigma, h3 and h4.

Usage

GH.moments(x0, sigma, h3, h4)

Arguments

x0, sigma, h3, h4

Parameters of the Gauss-Hermite series, as defined by van der Marel & Franx (1993)

Value
