The polynomial curve - fit method of Gallington and the direct - interpolation method of Zilliac were applied to the same set of calibration data, for a range of calibration grid spacings. The results showed that the choice of data - reduction method and the choice of calibration grid spacing each have an influence on the measurement uncertainty. At high flow angles, greater than 30 deg, where flow may separate from the leeward side of the probe, the direct - interpolation method was preferable. At low flow angles, less than 30 deg, where flow remains attached about the probe, neither data - reduction method had any advantage. For both methods, a calibration grid with a maximum interval of 10 deg was recommended. The Reynolds - number sensitivity of the probe began at Re = 5000, based on probe diameter, and was independent of the data - reduction method or calibration grid spacing.
