| 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. p SkyView also has two other sets of surveys derived from the RASS data with substantially higher resolution. The surveys whose names begin with RASS3 are counts maps with 45" pixels. The RASS or RASSInt surveys are intensity maps generated by dividing the counts maps with the exposure maps provided by MPE. ]] |
