“The ESA XMM-Newton Science Operations Centre: Making Basic Space Science Available to the Whole Scientific World”

XMM-Newton is a major X-ray observatory of the European Space Agency (ESA). Its observing time is open to astronomers from the whole scientific community on a peer reviewed competitive basis. The Science Operations Centre, located at ESA’s premises in Villafranca del Castillo, Spain, is responsible for the instrument operations, as well as for all the tasks related to facilitating the scientific exploitation of the data which the mission has been producing since its launch in December 1999. Among them, one may list: distribution of scientific data in different formats, from raw telemetry, up to processed and calibrated high-level science products, such as images, spectra, source lists, etc;development and distribution of dedicated science analysis software, as well as of continuously updated instrument calibration;regular organisation of training workshops (free of cost), for potential users of XMM-Newton data, where the procedures and techniques to successfully reduce and analyze XMM-Newton data are introduced;access to the data through state-of-the-art, in-house-developed archival facilities, either through the Internet or via CD-ROM;continuously updated documentation on all aspects of spacecraft and instrument operations, data reduction and analysis;maintenance of a comprehensive set of project web pages;a competent and responsive HelpDesk, providing dedicated support to individual XMM-Newton users.
