This is one of two possible models that equally fit the data. The second one is a 1k collinear model (see #1.392). A third alternate non-collinear model, with assumedly lower symmetry, proposed in the reference as it equally fit the data, is in fact a domain-related arrangement equivalent to the one here, having the same symmetry (with a different location of its standard origin with respect to the parent structure).
