ON THE ACCURACY OF CERTAIN APPROXIMATIONS FOR THE CHAPMAN FUNCTION.
Abstract
Practical approximations for the Chapman function over the entire range of possible solar zenith angles are considered. The approximations are numerically evaluated for a selected number of parametric values. Comparison with the Chapman function on a percent difference basis is provided. Some practical points regarding geometry are discussed for angles exceeding pi/2. (Author)
