1k magnetic structure
k-maximal magnetic symmetry (6 possible)
2-dim irrep along a special direction as primary
The  same irrep can yield a non-collinear spin arrangement of tetragonal symmetry, which probably could have also have fit the data.
It seems that this alternative model was not checked and contrasted with the data.
