There are two types of miniSPLAT files in this folder (dualhits.txt and sizepress.txt) and each are given for the pre, during, and post-expansions periods. Expansion 36 corresponds to expansion 1 in the paper, expansion 37 corresponds to expansion 2 in the paper, and expansion 38 corresponds to expansion 3 in the paper. The dualhits.txt file types contain individual mass spectra recorded during the experiments. Files are space delimited and from left to right have the number of the particle, the file extension where the raw data was located, the date and time the particle was measured, the time it took the particle to go from one sizing laser to another (which is converted to size in the sizepress.txt files), the total positive ion intensity, and the intensity for each mass to charge from 1 to 450 and -1 to -200. The sizepress.txt file types are tab delimited and contain from left to right the date and time the particle was measured, the size of the particle in nanometers, if the particle produced a mass spectrum or not (1 = mass spectrum, 0 = no mass spectrum), the PMT 1 count, the PMT 2 count, and the particle number concentration every second.
