XMM Users' Handbook

   
GO and GTO observations

XMM Guest Observer (GO) data will be protected for an initial period of one year after delivery to the GO. Precondition for the start of the proprietary period is the delivery not only of the data, but of all PPS data products, including in particular calibrated event lists.

Guaranteed Time Observers' (GTO) data are also protected for one year after delivery of the PPS products to the PI. For a list of GT targets, see below (Appendix D; Table ).

The proprietary period of an observation can be extended, if the calibration provided by the SOC at the time of delivery should a posteriori turn out to be inaccurate so that reprocessing of the data is required.
