What is Trajectory Deflection Angle ?
http://en.wikipedia.org/wiki/Flyby_anomaly

 

Um, the angle that the trajectory deflects?

Are you asking about the flyby anomaly itself, maybe?

From Anomalous Orbital-Energy Changes Observed during Spacecraft Flybys of Earth (PDF):

 

the deflection angle (DA) is the angle between the incoming and outgoing asymptotic velocity vectors

 

So it is the angle by which the trajectory is deflected.

Um, the angle that the trajectory deflects?

Right after swing by I geuss ?

I assume they mean the angle between the incoming and outgoing directions.

1.) Will it come data regarind Juno's flyby anomaly (if any) ?
2.) What is the inclination of the tracjetory of Juno ?
