Response to Morawiec's (1998) comment on Determination of a mean orientation from a cloud of orientations. Application to electron back-scattering pattern measurements

The authors had published two methods to compute the mean orientation from a cloud of orientations, as the problem practically arises when measuring individual orientations [Humbert, Gey, Muller & Esling (1996). J. Appl. Cryst. 29, 662-666]. This response recalls and outlines the main differences between their practical approach and the more general mathematical problem exposed by Morawiec in his comments [Morawiec (1998). J. Appl. Cryst. 31, 484].
