| MAJ_JUP_STELLAR_OCC | MAJIS will acquire several “subcubes” (number depends upon planet's speed over the sky) around the (fixed) star position, at different angular distances between the star and the planet's limb during the ingress/egress.
Each sub-cube spans over several lines (around 6, less if S/C capability allows it) to compensate for possible pointing inaccuracies.
Bright far moons can be used instead of stars as sources to decrease the repetition integration (and therefore spatial sampling) as the orbital velocity ranges from ~ 5 km/s at apojove to ~ 13 km/s at perijove
satellite orientation: LIMB TANGENT (preferred, otherwise VERTICAL), to minimize straylight

About 10min
66 sec (max) for each subcube. Time interval between sub-cubes as small as possible for better vertical coverage. Total number of cubes depends upon relative angular speed between star and limb. | MAJIS |

| SWI_ALLAN_TOTAL_CTS | Allan variance characterization of the CTS 1 & 2 by integrating on the cold
sky. Integration time is 1.5 s. | SWI |

| SWI_ALLAN_TOTAL_CCH | Allan variance characterization of the CCH 1 & 2 by integrating on the cold sky. Integration time is 0.1 s. | SWI |

| SWI_ALLAN_ACS_FS | Allan variance characterization of the ACS 1 & 2 by integrating on the cold
sky. Integration time is 1 s. Frequency-switch calibration method. | SWI |
|---|
| PEL_OFF_1 | All sensors off, only survival heaters on
PEP-Lo off (e.g. TCM, WOL periods) | PEPLO |
|---|
| SWI_OFF | All instrument subsystems including the DPU will be switched off. Consequently there will be no housekeeping data and no telemetry. The instrument will be in this mode during launch and cruise phase, except during calibration campaigns (e.g. planet flybys). | SWI |
