The data from each observation undergoes pipeline processing at the XMM-Newton Science Operations Centre (SOC), which produces a set of standard products for each observation. These products are available in the XMM-Newton Science Archive. The PI of each observation is informed immediately after successful pipeline processing via e-mail using the address provided via the XRPS. The associated appropriate calibration and auxiliary files can be obtained from the SOC web site. All products are kept in the XMM-Newton Science Archive and are made publicly available after expiration of the proprietary period (see section 9.1).
The data products reflect the state-of-the-art of XMM-Newton data analysis at the date of their production. However, subsequent improvements of the pipeline products and the corresponding calibration and auxiliary files are to be expected. In order to allow observers to benefit immediately from the improved understanding of the instruments, calibration files (as well as updated versions of the Scientific Analysis Software (SAS)) are made public on the SOC web-pages. This allows observers to reprocess their data.
Following the generation of data products, observers are responsible for further data processing as well as for the scientific analysis, interpretation and publication of their observations.
