Isotropic approximation of the distribution of mis-orientation angles

contiguous unit cells assumed to be perfectly aligned. Lower mosaicity

There are two types of twinning: merohedral or hemihedral

For merohedral twinning the diffraction patterns from the different domains are

twinning. It only involves two distinct domains. Pseudo-merohedral twinning is
a subclass merohedral twinning in which lattice is coincidentally superimposable.

In the case of non-merohedral or epitaxial twinning the reciprocal
lattices do not superimpose exactly. In this case the diffraction pattern
consists of two (or more) interpenetrating lattices, which can in principle
be separated.

Residual factor R for reflections that satisfy the resolution

reflections (i.e. were excluded from the refinement) when the

both values if a 'free' R factor were calculated for most of
