This dataset contains: MATLAB files with pressure and velocity fields for all experiments presented in the manuscript. In addition, the original MATLAB figure files are included.

The datset storage is as follows: Experimental test cases are stored in folders as SSSS_AA where 'SSSS' is the airfoil shape and 'AA' is the angle of attack. Each case contain five run folders e.g. run 1 is labeled 'R01'. Each run folder contains instantaneous fields stored as 'S*.mat' with u,v, and p corresponding to the streamwise velocity, cross-stream velocity, and pressure fields respectively in sequential order. In addition, a 'stats' folder is included with statistical fields and masks. Two masks are included, one 'mask.mat' corresponding to the airfoil cross section and one 'o_mask.mat' corresponding to the data that is visually occluded at the measurement plane.

The figures are as follows:
