The impact of projection effects on optical photometric galaxy clusterselection has recently been clarified at z virgul 0.1 using extensive spectroscopy ofputative member galaxies. The projected fraction of photometrically associatedgalaxies has been constrained in bins as a function of richness along with therelations between photometric and spectroscopically corrected richness andvelocity dispersion. We propose XMM-Newton observations of a complete sub-sampleof these clusters at high richness to obtain low-scatter X-ray mass proxies.These measurements will provide independent complementary information onprojection effects and crucially will allow the scatter of spectroscopicallycorrected richness with mass to be quantified.
