Comments:

NPD
Positional structure from a measurement at 50K
The direction of the canting component on the basal plane is undetermined. Here a direction which maximizes the symmetry is chosen.

Comments (symmetry):

1k magnetic structure
Two different irreps as primary: two different order parameters in the Landau sense are involved
