Abstract:

Analysis and methods of computation of the function yx, rho 2pi integral from 0 to infinity of exp-2x1rho - squarez - square dz1z - squared are presented. Power series, asymptotic series, and other expansions are developed for six regions of the positive quadrant of the x rho plane. These expansions allow efficient calculation of yx, rho to a relative accuracy of 0.01 or better. Author
