    • We note here that the extrapolated values of the (unrescaled) squared moments reported for the clean kagome system in Ref. are smaller than the true values by a factor of two. The origin of this factor lies in the choice of the x components of the spins for studying the correlations: the dominant eigenvalue of these correlations is twofold degenerate and corresponds to two modes with the same magnetization pattern in the x direction but with different chirality. By contrast, the correlation matrix C defined in Eq. 4 is able to select the state with the correct chirality, namely, that favored by the DM interactions.
