Spline interpolation leads to smooth looking graphs, but tends to oscillate making the method less suited for numerical calculations. Spline interpolation can not be used on the 2-dimensional gas tables that are produced by programs like Magboltz when a magnetic field is present.
The order of polynomial interpolation must be between 1 and the smallest of the two numbers: 10 and number of table entries - 1. Orders larger than 2 are not recommended.
