We propose observations of 4 galaxy clusters to finalize the detailedcharacterization of a complete RASS-selected sample of 24, spanning the redshiftrange 0.27 to 0.54. All clusters were observed by us in the SZ effect and inweak lensing. This is the first large, intermediate redshift, X-ray selectedcluster sample with SZE and lensing observations. It provides a uniqueopportunity to study the systematics of the hydrostatic mass estimates and ofselection effects from particular ICM probes. We will furthermore be able todetemine the evolution in both the normalization AND slope of themass-observable scaling relations, using Planck SZE measurements to calibratethe local values. Our clean X-ray selection permits to correct for the malmquist-bias in the process.

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.
