Median parallaxes for the LMC sample in Fig. 9 plotted against ν_eff in six magnitude intervals, as indicated in the diagrams. The orange points show the parallaxes of individual sources and give an impression of the coverage in ν_eff and scatter in parallax. The black dots, with error bars, show the median parallax and its uncertainty in bins of ν_eff with at least 20 sources per bin. The solid blue curves show the fitted combination of basis functions in Eq. (9) evaluated for a representative magnitude (G = 10.0, 11.5, 12.5, 15.0, 17.0, and 18.0) in each interval.
