XMM-Newton Publication Guidelines
When publishing a paper using XMM-Newton data please include the following text, preferably as a footnote to the title:
"Based on observations obtained with XMM-Newton, an ESA science mission with instruments and contributions directly funded by ESA Member States and NASA"
Each publication using XMM-Newton data should include the Target Name, the Date of the Observation and the Obs-Id to ensure that the data can be uniquely identified.
Publications using one of the XMM-Newton Catalogues should include the catalogue version and the unique catalogue name of each source used.
