Format of data: This is a spreadsheet with data about each experiment. The columns are labeled in the spreadsheet. The spreadsheet was made in Excel, but we've provided the data in several formats in case it is of use. In other words, each file has the same data.

The first few columns contain general information about the experiment: how many particles did we view on average, how much were the particles drifting (due to large-scale film flow), what particle size did we use, what was the film thickness, etc. The next few columns contain data on the single-particle diffusivity and inferred 2D viscosity of the film. The final columns contain data on the two-particle correlations and inferred 2D viscosity from those correlations. See our preprint for more information.

Note: Files updated January 30, 2015 to reflect minor changes in single-particle diffusion constants, now obtained using the CVE method of Vestergaard et al., Phys. Rev. E 89, 022726 (2014). doi:10.1103/physreve.89.022726
