Supplementary Material. Figures for each fluid.

Surface tension-temperature, absolute deviation-temperature, and percentage deviation -temperature plots for each fluid (ordered alphabetically). Discarded data (those not taken into consideration for the fit) are shown in grey in the surface tension plots, and they appear in the Di and PDi plots as grey points only if they are below Dmax and PDmax, in absolute value, respectively. Sources of data are also given for each fluid.
