The table listing the moment components in the paper is inconsistent with the text and Figure in the same article. Text and Figure have been assumed correct.

1k magnetic structure
Two different 1-dim irreps are active as primary irreps. 
The relative sign of the y component of the Nd spin, which is the only component of the arrangement corresponding to the second irrep mY1- is arbitrary. Its two possible values correspond to domain-related equivalent arrangements.
