Abstract The application of galaxy clusters in constraining cosmological models iscurrently mostly limited by our uncertain knowledge of scaling relations ofobservables and cluster mass. Most scaling relation studies are based on X-rayflux limited samples which are biased. In AO10 we proposed to take a newapproach with a study of an unbiased volume-limited sample. From this approachand a comparison of both types of samples we will get many new insights into thecluster property statistics. Of 47 AO10 targets 26 flared ones have beenresheduled for AO12 of which 6 are again severely affected by flares. Werepropose these last 6 targets to complete the volume-limited sample for a totalexecution time of 60 ks since it is crucial to have good data for the full sample.

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.
