The accuracy for this method largely depends on the spacing between the calibration points, and can be estimated using Equation 5.

Figure 4-17, Figure 4-18, and Figure 4-19 each show an example of a possible error curve for this setup with a different number of calibration points.

Figure 4-17 Two Sensors Lookup Table Calibrated Error, 14 Cal Points, ≈ 4° Peak-to-Peak Error

Figure 4-19 Two Sensors Lookup Table Calibrated Error, 45 Cal Points, ≈ 1° Peak-to-Peak Error

Figure 4-18 Two Sensors Lookup Table Calibrated Error, 26 Cal Points, ≈ 2° Peak-to-Peak Error
