David - There is a package by a norwegian colleague, called Janhunen, that I have used quite successfully for some nonlinear fits to functions such as A Exp[ B x + C] where A,B,C are the fit parameters. The method is used called something like "Lev..-Marquardt" and can be found e.g. in Numerical Recipes. The packages is on yoda under the directory JANHUNEN. Hope this helps, Rudo ################################################################# # Rudolf A.
