Unimodal Meridional Reflection Intensity

If the smeared image of a point-reflection on the meridian is unimodal, the orientation distribution g( p) is readily accessible. In this case a texture measurement through the reflection, = c) contains the information sought-after [256] 

In Fig. 9.5 two sides of the spherical triangle merge ( ep = ep), which leads to the result. Thus the shape of the meridional reflection at constant s directly reflects the shape of the orientation distribution.
