Abstract This paper presents an initial version of the diffuse background results from the ROSA T soft X-ray all-sky survey. These maps cover ∼98% of the sky in the ¼ keV, ¾ keV, and 1.5 keV bands, with ∼2° angular resolution and high sensitivity for low surface brightness extended features. The effects of non-X-ray contamination and X-rays of solar system origin have been eliminated to the greatest possible extent, but discrete X-ray sources have not been removed. The much improved angular resolution, statistical precision, and completeness of coverage of these maps reveal considerable structure over the entire 0.1-2.0 keV energy range that was not observed previously. The data agree well with previous all-sky surveys in terms of absolute normalization and zero point.
