We propose XMM-Newton observations of two clusters of galaxies, Abell 545 andAbell 697, at 30 ks each. The two will complete the XMM observations of oursample of 15 clusters with good Sunyaev-Zeldovich measurements. With theavailable or impending gravitational lensing data, this sample will aid indetermining many cluster scaling relations, and thus will be valuable for thefuture uses of clusters in cosmology.

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.
