| Scattering :
	 
	To visualize the scattering select in menu  the command
	<Parameters> next "Scattering". 
	The window below display the 50 last scattering observed per WMeteor. 
	This command is very helpful to evaluate the threshold to use on your
	installation. 
	In our example below teh threshold is at 10, but he would be able to decrease
	at 6 for an very sensible count or increase at 15 for an count who excludes
	the interferences. 
	The "big peaks" it is the echoes ! 
	When the 50 measures of scattering are passed the diagram use the Drift scan
	display, 1st data is removed by the 2nd etc... and the last data is at
	right.  |
