CAL- The PSF of the EPIC MOS is checked against the AXAF PSF calibration targetPKS0312-770, which has a source flux sufficiently low to avoid pile-up. A modestexposure allows the core of the PSF in MOS to be well-studied and provides areference against the PSF obtained with brighter sources, and with the higherresolution CHANDRA cameras. In the current plan only one off-axis pointing isscheduled because PSF cores at various field angles is covered eitherserendipitously or via other CAL observations.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
