Derived mass-loss rate as a function of the luminosity of each RSG candidate in the LMC. The colour bar shows the best-fit τ_V. The grey triangles represent the upper limits of targets fitted with the lowest values of the optical depth grid, and the open circles indicate the RSGs with spectral classifications. The dust-enshrouded RSG, WOH G64, is labelled with a red star. The position of the kink is shown with a dashed vertical line at log(L/L_⊙) = 4.42.
