We request 382 ks data for 12 clusters to complete our survey of avolume-limited sample of 55 clusters. We investigated the existing data, whichhints a mass dependent bias in the X-ray to weak lensing mass ratios fordisturbed ones. X-ray mass proxies, e.g., Yx, show low scatter, but the bestfits, particularly the slopes, of the mass-observable relations may be biaseddue to this mass dependence. Our program will quantify any mass/radial dependentbias based on three independent probes (X-ray/lensing/velocity dispersion) forsuch a volume-limited sample, and deliver definitive constraints on systematicsfor upcoming cluster cosmology surveys. The dataset will be a major asset forprograms aiming to measure dark energy and programs adding a multi-wavelength focus to studies of cluster physics.

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.
