The archive file PhasePOPS_Data.zip contains all the data collected from transition temperature measurement experiments. All data files are in .csv format. Files in PhaePOPS_size are for size-dependent measurements of sucrose discussed in section 2.3 of the paper. Data from POPS and temperature controller was collected on separate systems. There is a single file for POPS which includes data for all size-dependent measurements and multiple files for temperature controller data, sorted by the date of performed experiment. The metadata file in each folder explains the variable column used in the data file/s. Files in PhasePOPS_mixtures are for sucrose, citric acid, and tartaric acid mixture experiments. The sampling strategy is discussed in section 2.4 of the paper. A single file includes all data for performed experiments from POPS, DMA and temperature controller. The attached metadata file explains the variable column in data file.
