MAJIS internal calibration using 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)

Pointing: MAJIS scan mirror oriented towards the ICU (8.5°)
Satellite orientation: Deep space
Duration: 10min




Once per month (TBC)
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc
conditions that make the observation not possible (e.g. thruster firing)
