| Description: i The following is adapted from the MPI FTP site information: 7/16/97 /ibr These maps present the initial version of the results from the ROSAT soft X-ray all-sky survey as presented in ApJ 454, 643. The maps cover approximately 98% of the sky in the 1/4 keV, 3/4 keV, and 1.5 keV bands, with about 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 reveals considerable structure over the entire 0.1-2.0 keV energy range that was not observed previously. The data compare well with previous all-sky surveys in terms of absolute normalization and zero point. These maps may be used for scientific purposes as long as reference is made to the relevant publication |
