Euclid/VIS stellar flux density map, based on Gaia (Gaia Collaboration 2016, 2018) and Sahlmann et al. (2016) catalogs: Black contours: footprint of a proxy of the Euclid/VIS Survey (Scaramella et al. 2021). The darkened regions, corresponding to the peak of the Milky Way emission, lie outside the footprint. The three regions marked with orange contours correspond to the Deep North, Deep South, and Deep Fornax fields. Color background: stellar flux density per HEALpix cell. The brightest region corresponds to the Galactic plane, a region avoided by the Euclid footprint. See the bottom color bar for the scaling. Red lines: projected trajectories of the main Solar System bodies (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) as seen by Euclid during the mission, following the ecliptic plane (Giorgini et al. 2001).
