Scheduling rules:

Spacecraft downstream of moon with respect to corotating plasma flow.
Spacecraft within 15 degrees jovigraphic longitude of moon location.
Spacecraft on dipole L-shell within 0.03 of dipole L-shell of moon orbital path.

Contextual Parameters:

Comments:

Opportunity implementation in geo-pipeline:
whenever the flag traj_data."moon"_wake is > 0
Computation of the moon_wake flag is done as follow:

;;
;; The moon wake observation condition has three components (in order of importance):
;; i) SC downstream of moon with respect to corotation direction
;; ii) <= 15 degrees jovigraphic longitudinal separation
;; iii) a miniumum dipole L-shell separation of SC from moon orbital path
;;
;; INPUT: t_et - ephemeris time
;; sc - spacecraft e.g. JUICE
;; moon - name of the moon being considere (Galilean moons except Io)
;;
;; OUTPUT: moon_wake_obs - boolean stating whether or not the condition
;; observation condition is met. 1 OR FALSE .
