History

Mnemonic:

MAJ_JUP_RING

Name:

Radial (and azimuthal) structure of the main rings region (low elevation (~<0.5deg) at a given phase angle

Description:

Observations of the main rings (2 ansa) at a given phase (backscattering to forward scattering light), no tracking of azimuthal structure, no spatial binning to increase spatial resolution

Payload:

MAJIS

Advanced

Scheduling Rules:

Low elevation (~<2°), near 0° highly preferred, eclipse, 2 ansa
Acquisition at far distance (>8.105 km at closest approach) to mitigate the spikes issue (<1 e- impacts/s) constraining the resolution (IFOV>=120 km before binning)
100 kHz readout mode (lowest RON < 30 e-)

any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc

Avoidance Rules:

n/a

conditions that make the observation not possible (e.g. thruster firing)
