Class ParticlePoint

java.lang.Object

iceCube.uhe.points.ParticlePoint

All Implemented Interfaces:

java.io.Serializable

public class ParticlePoint
extends java.lang.Object
implements java.io.Serializable

    This class contains the variables and methods concerining
    the particle location and the propagation medium.

    Calculations on propagation of UHE particles in the rock/ice require
    the point vector that is provided by this class.
    It also provides the parameters of the medium such as the density
    which are used for the cross section calculation made in
    the Interaction class.

    The parameters provided in this class are:

    The vector of the particle location--
        R     : Radius from the earth center.
        lAxis : Length along the propagation axis
                from the incident point to the current particle location.
        theta : Zenith angle [rad]
        phi   : Azimuth angle [rad]
        alpha : Nadir angle [rad]
                Those angular parameters above are defined
                at the point where a particle emerges from underground.
        MaterialNumber: ice (0) rock (1)

        These are based on the Standard Earth Model
        and the related geometrical factor.

    The parameters of the material at the particle location--
        Density : Mass density [g/cm^3]
        Xslant  : Slant Depth: [g/cm^2]
            For each component..
               Atomic Number
               Charge
        Material name (Rock, ice, etc.)

             Material Number  0   1
Madium                       ice rock
Number of Species             2   1
