Class HillasParameters

java.lang.Object

fact.features.HillasParameters

All Implemented Interfaces:

stream.Processor

public class HillasParameters
extends Object
implements stream.Processor

Calculate the classical hillas parameters on a PixelSet. Calculated are size, length, width, delta, the cog, and the higher moments m3, m4, skewness, kurtosis each for longitudinal and transverse shower coordinates.
