The data acquired during satellite slews are used to build the XMM-Newton Slew Survey Catalogue, which was first released in April 2006 as XMMSL1. Updates were made on a yearly basis culminating in a new version, XMMSL2, which went public in March 2017. All the data contained in XMMSL2 are fully integrated in the XSA. The catalogue has been built by members of the XMM-Newton SOC and the EPIC consortium on behalf of ESA. The description of the catalogue and all relevant documentation, including sky coverage, number of sources and flux limits in different bands can be found in the XMM-Newton Science Archive web page. Further information can be found in Saxton, R. D. et al. 2008, A&A 480, 611 and references therein.
