Mnemonic:

MAJ_JUP_LIMB_SCAN

Name:

MAJ Jupiter Limb Scan

Description:

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

Payload:

MAJIS

Pointing

Pointing Type:

limb

Target:

Jupiter atmosphere

PTRSnippet file:

Advanced

Scheduling Rules:

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

Avoidance Rules:

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)

Maximum estimate is obtained assuming 508 spectels and 508 spectels for VISNIR and IR respectively. 5 bits/data element compression factor is considered. It is also assumed that only the central 64 pixels of each slit are transmitted on ground. Data rate reduction factor: x 1-0.5, from spectral editing 9472 -> update post PJ12.
