    // Add the maximun number of iterations in GaussNewtonOptimizer
    GaussNewtonOptimizer optimizer = new GaussNewtonOptimizer(false);
    PolynomialFitter fitter = new PolynomialFitter(5, optimizer);
    for (int i = 0; i < data.size(); i++) {
        if ((Double) batches.getPeak(names.get(i)) == batch) {
            Double point = data.get(i);
            fitter.addObservedPoint(1, (Double) runOrder.getPeak(names.get(i)), point);
