Class StateVec

java.lang.Object

Jama.Matrix

org.jlab.rec.dc.trajectory.StateVec

All Implemented Interfaces:

Serializable, Cloneable

public class StateVec
extends Jama.Matrix

A StateVec describes a cross measurement in the DC. It is characterized by a point in the DC tilted coordinate system at each wire plane (i.e. constant z) and by unit tangent vectors in the x and y directions in that coordinate system. The state vector parameters are the plane index, (x, y, tanTheta_x, tanTheta_y). [The tilted coordinate system is the sector coordinate system rotated by 25 degrees so that the z axis perperdicular to the wire planes]
