How many data points are they using to get the fit? With 17 harmonic terms they have 53 degrees of freedom in their equation. This feels very much like a case of adding too many terms to your equation so that it's bound to fit the data. I've had some nasty experiences because someone decided to fit a fifth-order polynomial to some data without looking at the results (electrical efficiency was swinging between -300% and +400%). -- Clive D.W.
