Rev. B \\textbf{28}, 784 (1983)] are a common tool for local structure characterization in soft matter studies. Recently, Mickel \\emph{et. al.} [J. Chem. Phys. \\textbf{138}, 044501 (2013)] highlighted problems of the bond orientational order parameters due to the ambiguity of the underlying neighbourhood definition. Here we show the difficulties of distinguish common structures like FCC- and BCC-based structures with the suggested neighbourhood definitions when noise is introduced.
