Table 1 Fitted layer parameters for dodecane-\(\hbox {d}_{26}\) entrained against an iron-coated silicon substrate at 7.0 \(\times\) 10\(^{2}\) \(\hbox {s}^{-1}\). The central parameter values are the median values obtained from the bootstrap routine, with the 95% confidence intervals reported in the sub- and superscripts. Those values without uncertainties were held constant. \(^{{\text {a}}}\)Parameters used to model the sheared layer. \(^{{\text {b}}}\)Parameters used to model the non-sheared layer.
