Curve-of-Growth Function for a Random Array of Voigt Lines.

Abstract

The accuracy of two approximations to the curve-of-growth function V(a,x,) for a random array of Voigt lines with exponential line strength distribution is examined. An heuristic extension of the approximation for isolated Voigt lines is accurate to better than 9% for all x and a. A modified version of the approximation used in the NASA plume radiation code is accurate to better than 4% for all x and a.
