Lumb %J Physics %D 2000 %I arXiv %R 10.1117/12.391615 %X The in-orbit imaging performance of the three X-ray telescopes on board of the X-ray astronomy observatory XMM-Newton is presented and compared with the performance measured on ground at the MPE PANTER test facility. The comparison shows an excellent agreement between the on ground and in-orbit performance. %U http://arxiv.org/abs/astro-ph/0007256v1
