    6565== Example of an intense vortex ==
    66 With the GUI '''uvmat''' open an image in '/UVMAT_DEMO04_PIVchallenge_2001A/images' taken from PIV challenge ([http://www.pivchallenge.org/ see website]). A short description of the experimental conditions is given in the file 'readme.txt' in the folder of the images. It is said that the flow seen in the image is the vortex behind a airplane. In term of PIV features, it represents a case with poor particle seeding in the vortex core. It is said that the field of view is 170 x140 mm, so that, since the image size is 1280x1024 px, the scale is 7.4 px/cm. but there is no information about the time interval Dt.
