When classifying the data according to the distance of the methyl group to the backbone, it seems that the order parameters at the Cγ methyl show practically the same correlations to the amide motion on the same residue as the Cδ methyl groups (e.g., ri(γ) = 0.50 vs. ri(δ) = 0.46). The slope of the linear correlation is, however, roughly twice for Cδ compared to Cγ, indicating that the methyl group motion transfer are significantly dampened through the degrees of freedom of the linear side chain.
