Comments:

NPD
Position structure from a determination at room temperature by another study
The MSG type assigned in the article is not correct. The required propagation vector is (1,0,0) and not (0,0,0) and necessarily results in a MSG of type IV.

Comments (symmetry):

1K magnetic structure
k-maximal magnetic symmetry
1-dim irrep
