XMM-Newton Guest Observer Facility

How to choose the right mission for your research


The GOF has assembled the table below in order to help students and scientists who might want to propose for time, but are unfamiliar with NASA's high-energy missions. XMM instruments and their specifications are in blue, while the specifications that are most useful for a given study are in orange.

Please note that this is intended as a general pointer, and potential PIs should first carefully consider their science and each missions' strengths and weaknesses before making any decisions.
