Figure 4
A schematic representation of the arrangement of the diffraction geometry. [omega]

is the angle between the incoming beam direction and the specimen surface, [theta]

_hkl is the Bragg angle of the hkl reflection, e_hkl is the normal unit vector of the hkl planes, and [theta]

is the angle between e_hkl and the normal of the measured specimen surface, z. The y coordinate lies on the specimen surface. The dashed cone indicates schematically the angular range, 2 [Delta]

_hkl, within which the hkl reflecting planes correspond to the same texture component. The 2 [Delta]

_hkl values are correlated to the value of m.r.d.
