This sub-collection contains the raw PIV images that were used to track plate position. After unzipping the compressed files, you will have two folders; one for each case (acceleration over one or six chords). Within each are a sub-folder containing the images and an associated movie. The images are stored as TIFF files, numbered sequentially from B00001. The image sampling rate is 100Hz, and the field of view is 351.6mm square. The view orientation is the same as presented in the paper (cf. figures 1 and 3).
