MAJ_JUP_LIMB_SCAN
MAJ Jupiter Limb Scan
The MAJIS pointing mirror is used to scan the atmosphere of Jupiter over the limb up to 1500km. Exposure times are optimized for weak limb emissions.
The scan mirror step of 1/10 MAJIS IFOV shall constrain the spatial sampling provides a spatial supersampling adequate to reconstruct, by deconvolution, the signal vertical profile at sub-pixel scale.
Observations consists in sets of max. 8 cubes at different latitudes, around the limb of the planet.

Duration: Typically 20 min for each cube (110 lines), assuming 11 s per line

Scheduling rules, that requires these observations at 0° and 90°, ensures that the sun avoidance distance is always met.
Distance from Jupiter > 1 e6 km is favoured to avoid despiking issue and allow long Tint
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc
Conflict with downlink or moon flybys because of their length (high exposure times, high number of lines)
conditions that make the observation not possible (e.g. thruster firing)
