Observation Definitions
Observation definitions:
Advanced
Scheduling rules:
- whenever distance is <7.0E+5 km
- Phase angle <110deg
- Star in JANUS FoV at same magnitude than Elara
- Jupiter NOT in JANUS FoV
- Repeated for each moon 2 to 3 times, repeated at different true anomalies and different phase angles
- Duration: 2 hours (1 hr for pointing, 1hr for MAJIS cube) centered on CA
Contextual Parameters:
Comments:
Opportunity implementation in geopipeline for Amalthea/ Thebe/ Adrastea/ Metis
Distance to moon < 7e5 km
Maximum phase angle: 110 deg
+-1 hour around CA
Additonal filtering:
;;If Jupiter is in Janus FOV at any time during the segment, we reject the segment
;;check whether the sc-moon/sc-Jupiter angle is always larger than
;the Jupiter half-apparent diameter + half- the Janus FOV [full FOV is 1.72 x 1.29 degrees, so we take 1.72/2 = 0.86 deg]
;;If this is not the case, we reject the segment
