The remaining dataset contained 28,734 measurements. We removed any dye-solvent pairs with duplicate measurements within the same dataset that disagreed by more than 5 nm. For those that agreed within 5 nm, the mean of the values was used. This resulted in datasets of size 1,825 (CDEx), 3,840 (ChemFluor), 14,771 (Deep4Chem), 1,720 (DSSCDB), 3,025 (DyeAgg), and 24,580 (a combined set of ChemFluor, Deep4Chem, DSSCDB, and DyeAgg).
