This table contains the 'clean' sample of sources from the third catalog of X-ray sources found in slew data taken by the European Space Agency's XMM-Newton Observatory, XMMSL3 or XMMSLEW, Version 3.0. It has been created by the XMM-Newton Survey Science Center (SSC) on behalf of ESA, building on previous work carried out by the XMM-Newton SOC. The core <a href="/W3Browse/xmm-newton/xmmslewful.html">XMMSL3</a> catalog contains detections drawn from 3120 XMM-Newton pn slew observations, covering an energy interval from 0.2 keV to 12 keV. These observations were made between 2000 August 26 and 2023 August 11. All slew observations are public. A full discussion of the differences between XMMSL3 and XMMSL2 is given in Section 12 of the <a href="http://xmmssc.irap.omp.eu/Catalogue/XMMSL3/XMMSL3_Catalogue_User_Guide.html">XMMSL3 Users Guide</a>. This database table was first created by the HEASARC in August 2007 based on the FITS version of XMMSL1D1 (v1.1) of the XMM Slew Catalog. The current version was ingested in February 2025 and is based on the FITS version of XMMSL3 (v3.0) of the XMM Slew Catalog obtained from the following URLs: <a href="http://xmmssc.irap.omp.eu/Catalogue/XMMSL3/xmmsl3_v1.0.fits">http://xmmssc.irap.omp.eu/Catalogue/XMMSL3/xmmsl3_v1.0.fits</a>; (the total sample). This catalog contains only the entries from that FITS file which have VAL_FLAG = 'CLEAN SAMPLE'. <p> The HEASARC has endeavored to retain the same parameter names as in the ESA version, but some names have been changed so as to conform to the standard HEASARC parameter naming conventions, e.g., all error parameter names which ended in "_err" in the ESA version end in "_error" in this HEASARC version. For other parameters which have had their names changed, their original ESA names are listed in square brackets in their descriptions below. This is a service provided by NASA HEASARC .
