The pointing and alignment performance of the XMM spacecraft will have a very strong influence on the quality of the scientific results obtainable. The pre-launch unit and subsystem tests and subsequent analyses have shown that the scientific requirements will indeed be met with comfortable margins and the performance goals will be met for more than 90% of all anticipated observations.
