I've also used Excel, believe it or not. Mathematicians tend to define "best" in terms of least squares, but often (at least in instrumentation design) what you want to minimize is the maximum abs. value of error everywhere within a range. I have access to Mathcad these days, so I might try that if Excel didn't work. Best regards, Spehro Pefhany -- "it's the network..."
