We have updated and improved the source catalog obtained from the ROSAT all-sky survey. In this new version of the source catalog (Second ROSAT all-sky survey, 2RXS), we have made a number of improvements, paying particular care to reduce spurious sources. The final catalog contains about 135,000 X-ray sources, thereby providing the deepest and cleanest all-sky survey to date. For each source, new data products, including spectra and light curves, were created, allowing to take full advantage of this catalog for new scientific explorations.
