Abstract:

The accuracy of two approximations to the curve-of-growth function Va,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.
