MAJ_JUP_LIMB_SLEW
MAJ Jupiter Limb Scan performed with a S/C 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)

Pointing

Slew
Jupiter atmosphere

Advanced

Best performed at 90° phase angle (subsolar and antisolar meridian at limb) Distance from Jupiter >1 .106 km to avoid despiking issue and allow long Tint Conflict with downlink or moon flybys because of their length (high exposure times, high number of lines)
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc
TBD
conditions that make the observation not possible (e.g. thruster firing)
