Texture measurements in polycrystalline 123 oxide superconductors are complicated by the superpositionof Bragg reflections in the pole figures due to the near degeneracy of the crystal structure. Amethod is described, based on an extension of the WIMV algorithm, for resolving thesesuperpositions and determining the crystal orientation distribution (OD). The method is exemplifiedby OD analysis of a magnetically aligned, strongly textured powder sample of YBa 2 Cu 3 O 7 .
