Fig. 3.

Average relative strain error, ${\epsilon }_{\mathrm{err}}$, increases linearly with respect to the capped maximum marker displacement error magnitude. The error ratios, as shown in each subfigure, depend on the marker configuration. Inset shows the standard deviations when displacement random errors are capped at the ±10% level. Numbers in subfigures indicate the fitted line slope for the corresponding element type.
