Nightjar wake flow fields

This data constitutes of flow fields capturing the wake behind European nightjars (Caprimulgus europaeus) flying in a wind tunnel. Most of them are for one wing and the body only. The data is captured using stereo particle image velocimetry in a plane perpendicular to the free stream flow of the wind tunnel. The planes are then stacked and the files stored here represent volumes. We defined a righthanded coordinate system with x in the downstream direction and z vertically upwards. The data consists of six columns, three giving the coordinates (m) of the vectors and three giving the flow (m/s) along the different axes.
