| MAJ_JUP_LIMB_SLEW | The scan the atmosphere of Jupiter over the limb up to 3000k is performed with a specific slew of the S/C
Individual lines are largely overlapped to provide actual supersampling (x 10) in the spatial domain and allow sub-pixel resolution by deconvolution.
Typically, we have cubes of about 300 lines by 50 pixels (~7500 km)
Pointing type:
OFF-NADIR (nominal pointing position over the Jupiter limb), continuous tracking (‘track tangent limb’)
satellite orientation:LIMB TANGENT (MAJIS slit tangent to the limb), very slow s/c slew to get oversampling (10 lines corresponding to one pixel IFOV)
Duration: 55 min for each cube (300 lines) | MAJIS |

| SWI_2D_MAP_PS_V1 | This is a multi-purpose mode that can be used on any science target for
any 2D mapping, and meridional or zonal rasters. This mode will also be used for calibration
purposes (e.g. pointing). The number of rows and columns and the stepsize of the raster map is adaptable to the target angular size. Jupiter: Investigation of the global and regional stratospheric
composition and temperature of Jupiter, and pointing calibration. For 2D maps, meridional
scans and zonal scans, two CTS spectra are recorded for 60 seconds over 10000 channels
(16 bits coding). Moon monitoring: Investigation of the spatial distribution of Galilean moons
atmospheric species (+ monitoring), and calibration. Two CTS spectra are recorded for 60 seconds
over 210 channels (16 bits coding). Flybys: Mapping of Galilean Moons’ surface properties
and atmospheric composition, temperature, and winds. Two CTS spectra are recorded for 30 seconds
over 210 channels (16 bits coding). GCO: (1) Investigation of Ganymede’s atmospheric
composition, temperature, and winds, and surface properties by scanning from limb to limb with
the along-track mechanism across the ground-track using the antenna mechanism ( 72 ). Two
CTS spectra are recorded for 10 seconds over 130 channels (16 bits coding). (2) Tomographic
investigation of Ganymede’s atmospheric and surface composition, temperature, and winds by
scanning along-track from 30km to +30km of the nadir axis with 9 steps, using the rocker
mechanism ( 4.3 ), and with 1.5 sec integration time for two CTS spectra over 130 channels
(16 bits coding). In all cases, two CCH measurements (20 bits coding) are recorded for 0.1
second. During GCO, this implies that two CCH measurements are separated by 1/2 beam at
1200 GHz. Position-switch calibration method (the OFF position is observed after each ON of
the map is observed). | SWI |

| UVS_JUP_HP_FEATURE_SCAN | To assess the evolution of discrete phenomena (e.g., H Ly-alpha bulge, plumes, auroral features,…) using the HP port and pixellist mode. | UVS |
|---|
| MAJ_ICU | To monitor the radiometric performances of MAJIS using VISNIR and IR sources Specifically, there are several goals
A) tracking the evolution of the actual levels (before subtracting for CDS) in the digital dynamics (0-65535 at 100 kHz, 0-4095 at 1 MHz). Such an evolution could lead to adjust an offset which can be selected by TC (4 settings) so as to avoid reaching digital saturation for the read image before analog saturation.
B) tracking the evolution of the dark current and cosmetics (new hot / dead pixels)
C) tracking the evolution of the overall photometric response as a function of the signal (needed for the pipeline)
