Instructions for the analysis of case B: 
Strong vortex
28.10.2000 		okamoto@tokai.t.u-tokyo.ac.jp


Flow Field
* The flow field was strong vortex generated on the computer.
* The field parameter is not known.


Image generation
* The particle scatter was assumed to be the gaussian distribution.
* The occlusion particle was considered.
    The intensity of the particles were linearly added.
* Fill factor was assumed to be 0.7.
* Particle diameters were randomly determined.
    The histogram of the particle diameter was gaussian distribution.
* Laser light sheet intensity was assumed to be gaussian.
    Maximum out-of-plane velocity was set to be about 30% of
    laser light thickness.
* The image  size is 512 x 512 pixel. They are provided in tif format with a 
    header of 509 bytes.
