We conduct a joint analysis of observation from the Chandra and XMM-Newton X-ray telescopes of 30 relaxed clusters. The spectra are extracted and fit with a spherical gas distribution in equilibrium with a generalized NFW profile. Key fit parameters include the total mass and the logarithmic slope and and concentration of dark matter profile in the cluster. Separate fits to the plasma thermodynamic properties without assuming hydrostatic equilibrium are also made. We present results on the mass-concentration, mass-slope, and concentration-slope relationship for the sample.
