3. Package 3
   Author: B.Wieneke
   Sequence of experimental time-resolved PIV images showing a slightly turbulent air flow with small water droplets with a diameter of about 5 micrometer. The sequence has been recorded with a Photron APX camera with 1024 x 1024 pixel running at 1000 Hz. The field of view is about 7 x 7 cm.

4. Package 4
   Authors: B.Wieneke, LaVision and F.Scarano, TU-Delft
   Synthetic PIV image with different flow gradients and noise This image is used in the current PIV-Challenge 2005 (case A4) It has been designed in a way to analyse the capability of 2D-PIV algorithms to cope with different degrees of local flow gradients without and with varying degrees of image noise. The purpose was to design a single image which shows immediately in a visual as well as quantitative way the strengths and weaknesses of a particular algorithm.

5. Package 6
   Author: B.Wieneke,
   This data set contains synthetically generated volumes with seeding particles. Volume size: 512 x 513 x 33 voxel (nx,ny,nz). The source 2D-images and calibration data are also provided. It is a good starting point to test ones tomographic reconstruction, 3D-cross-correlation or particle tracking algorithms.

6. Package 9
   Authors: F.Scarano, TU-Delft and D.Michaelis, LaVision et.al.
   Experimental volume PIV-data. This data package contains of two volumes computed by tomographic reconstruction (Tomographic-PIV).It is a Karman street behind a cylinder, which is positioned to the right of the volume, with the water flow going to the left.

7. Package 10
   Author: B.Wieneke,
   Experimental LIF images. The supplied sequence of 20 images has been recorded in water where another fluid with a certain fraction of carbonoxy snarf which is pH-sensitive. The images have been illuminated with a laser light sheet at 532 nm detected by two cameras having filters for two different wavelength ranges (image set SNARF-1 and SNARF-2). The ratio of the two intensities is proportional to the pH-value (set SNARF-pH).
