Following on our previous study of an analytic parametric model to describethe baryonic and dark matter distributions in clusters of galaxies withspherical symmetry, we perform an SZ analysis of a set of simulated clustersand present their mass and pressure profiles. The simulated clusters span awide range in mass, 2.0 x 10^14 Msun < M200 < 1.0 x 10^15Msun, and observationswith the Arcminute Microkelvin Imager (AMI) are simulated through theirSunyaev- Zel'dovich (SZ) effect. We assume that the dark matter density followsa Navarro, Frenk and White (NFW) profile and that the gas pressure is describedby a generalised NFW (GNFW) profile. By numerically exploring the probabilitydistributions of the cluster parameters given simulated interferometric SZ datain the context of Bayesian methods, we investigate the capability of this modeland analysis technique to return the simulated clusters input quantities. Weshow that considering the mass and redshift dependency of the cluster haloconcentration parameter is crucial in obtaining an unbiased cluster massestimate and hence deriving the radial profiles of the enclosed total mass andthe gas pressure out to r200.
