double Geom::deltaBarePhi ( double  phi1,
double  phi2 
) [inline]

Find aximutal Angle difference between two generic vectors ( v2.Phi() - v1.Phi() ) The only requirements on the Vector classes is that they implement the Phi() method

Parameters:
v1Vector of any type implementing the Phi() operator
v2Vector of any type implementing the Phi() operator
Returns:
Phi difference

\[ \Delta \phi = \phi_2 - \phi_1 \]
