It's best to send these questions to the GSL discussion list. So I have CC'ed my reply there. These were computed in Mathematica, using a script which I have long since lost; it was done about ten years ago. But I'm not sure what you want to do. The coefficients are well-defined, independently of the way they were computed. -- G. Jungman On Mon, 2009-09-07 at 11:15 +0200, Jens A.
