Example: Zero-field calibration data

In this example, we calculate Chebyshev coefficients from zero field calibration data for a commercially calibrated resistive thermometer. In later examples, we determine the corresponding coefficient values in non-zero magnetic fields.

Load Python packages for data fitting

For these fits, we use the  Chebyshev convenience class  routines included in the Numerical Python (Numpy) Polynomial package.    Please see the Numerical Python reference manual and the example code attached to Fig.\ref{249499} below for further details.
