Representation of eROSITA_DE sky in Aitoff projection in Galactic coordinates. The left panel shows the (vignetted) effective eRASSl exposure map with values ranging from ≈100 s (blue) at the ecliptic equator to more than 10000 s (yellow) close to the ecliptic pole. The right panel shows the LS10 footprint in the same projection and coordinates, covering 76% of eROSITA_DE. The locations of Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are shown for illustrative purposes.
