The selection functions of cluster samples used for cosmological studies has a crucial impact on the reliability of derived parameters. There is growing evidence that optically selected clusters are underluminous in X-rays, indicating larger X-ray selection biases than previously thought. We propose to address this with Chandra observations (totalling 231 ks) of 8 clusters selected in a Subaru weak lensing (WL) survey. This will complete a sample of 10 clusters that will be used to systematically study the X-ray properties of clusters detected independently of their baryonic content. We will measure the scaling relations of the X-ray properties (e.g. Lx, kT, Mgas, Yx), study the morphology/structure, and test the calibration of X-ray mass proxies for a sample of WL-selected clusters.
