where the values [mathematical expression not reproducible] are, respectively, the radius and velocity magnitude at the apocenter of a Jovian orbit with pericenter equal to the Europa semi-major axis, and period [4T.sub.Eu].
As an example, vertical displacements on the graph can be obtained as a result of a tangential impulse at the apocenter.
Here, a flyby permits to rotate the hyperbolic excess of velocity, allowing the probe to enter a Jovicentric orbit with a larger apocenter. A generic AV-EGA maneuver can be labeled as K : L(M) [+ or -], where K and L indicate the number of revolutions that moon and probe complete, respectively, before the next encounter; M [less than or equal to] L denotes the spacecraft orbit where DSM occours; the sign [+ or -] is used to distinguish between the possible encounter locations: just before (-) or after (+) traversing the line of apsides.
