We start at the minimum degree for the spherical expansion and fit until we surpass the maximal allowed RMS. We return null if this cannot be achieved within the defined maximum degree of the sphericals.

fTest

private double fTest(double ftest,
                     int l,
                     int n)

getF0

private double getF0(double chi2low,
                     double chi2,
                     int l,
                     int n)

parameterDeletion

private static int[] parameterDeletion(VectorG fitted,
                                       VectorG error,
