Data relate to the article appearing in Journal of Fluid Mechanics article "Self-similarity of fluid residence time statistics in a turbulent round jet." by Donghyuk Shin, Richard Sandberg, Edward Richardson. The data file is a zip directory containing one file relating to each figure in the article, numbered according to the figure number. Each file is a text file with data in column format and human readable column headings. The contour plots account for the majority fo the 90 MB size of the zip file. The line plots are much smaller.
