Opportunity implementation in geopipeline
Those segments are dedicated to the refinement of the ephemeris of Callisto during the mission
The opportunities of observation are:
;Minimum Sun-SC-Moon (exclusion angle: 30 deg)
;;Minimum Jupiter-Limb-spacecraft-Moon angle: 5deg for apparent size < 4 deg
;; 10 deg for apparent size > 4 deg
;; (CAUTION: in the FD document, the numbers are inverted but does not make sense)
;;Maximum Sun-Moon-Sc Angle (Phase): 130 deg
;;Minimum number of pixels in the navcam detector: 5 (for a Navcam FOV of 4 deg)
;;Maximum fraction of FOV allowed to be filled by the moon: 1/SQRT(5)
;;5 pixel out of 1024 (one dimension) to be filled by moon
;;1024 corresponds to 4deg FOV of Navcam
;;(5/1024)*4 = 1.9e-2 deg angular size minimum that must have the moon to be obsertved
The minimum effective duration of the segment is 1 hours (where the conditions above must be met)
There is no upper limit to the duration of this segment performed in the opportunity analysis
Filtering rules applied: NAV_EPHEM_XXX segments are not scheduled from -2 weeks to +12h of a Europa, Ganymede or Callisto Flyby CA
