Mnemonic:

ASTRO_IRR2_PASIPHAE

Name:

ASTRO_IRR2_PASIPHAE

Description:

astrometry measurement with inertial pointing to moon Pasiphae

Trajectories:

CReMA 3.0, CReMA 3.1, CReMA 3.2, CREMA_5_0, CREMA_5_0b23_1, CREMA_5_1_150lb_23_1

Observation Definitions

Observation definitions:

Advanced

Scheduling rules:

- whenever distance is <2.0E+7 km
- Phase angle <90deg
- Star in JANUS FoV at same magnitude than the observed moon
- 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)

Contextual Parameters:

Comments:

Opportunity Implementation in geopipeline
Minimum distance to Pasiphae: 2e7 km
Maximum phase angle: 90deg
+-1 hour around CA
Additional 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

--> mainly JANUS with colour imaging,
--> MAJIS will ride along to obtain IR spectra in the best opportunities (largest objects and closest distances being preferred)
--> SWI TBC
