org.das2.qds.demos.PlasmaModel

Model of plasma distribution function for given density, temperature, speed. A java.util.Random object is passed in so that the data may be reproducible (by using a given starting seed).

PlasmaModel( )

counts

counts( Datum energy, java.util.Random random ) → int

return the counts at this energy, assuming an isotropic distribution, and Poisson noise is added to the result.

Parameters

energy - in eV
random - source of random numbers.

Returns:

an int
