Resolved CXB fraction in eRASS1. Bottom panels: HEALPix order 4 map of the 1–2 keV CXB intensity resolved fraction (eROSITA-DE hemisphere, Hammer-Aitoff projection, in Galactic coordinates). On the bottom left we include all sources with DET_LIKE_0 > 10, no flags and X-ray flux F_0.5−2 keV > 1 × 10⁻¹⁴ erg s⁻¹ cm⁻². On the bottom right we include all sources with DET_LIKE_0 > 10, no flags and X-ray flux F_0.5−2 keV > 5 × 10⁻¹⁴ erg s⁻¹ cm⁻² (i.e. the hemisphere median flux limit at 50% completeness). Top panels: distribution of the resolved fraction in the extragalacitc sky (|b| 30°) in 13.4287 square-degree pixels for the two cases. The solid lines are the median values: 0.24 and 0.19, respectively.
