Mass and pressure constraints on galaxy clusters from interferometric SZ
  observations
  Following on our previous study of an analytic parametric model to describe
the baryonic and dark matter distributions in clusters of galaxies with
spherical symmetry, we perform an SZ analysis of a set of simulated clusters
and present their mass and pressure profiles. The simulated clusters span a
wide range in mass, 2.0 x 10^14 Msun < M200 < 1.0 x 10^15Msun, and observations
with the Arcminute Microkelvin Imager (AMI) are simulated through their
Sunyaev- Zel'dovich (SZ) effect. We assume that the dark matter density follows
a Navarro, Frenk and White (NFW) profile and that the gas pressure is described
by a generalised NFW (GNFW) profile. By numerically exploring the probability
distributions of the cluster parameters given simulated interferometric SZ data
in the context of Bayesian methods, we investigate the capability of this model
and analysis technique to return the simulated clusters input quantities. We
show that considering the mass and redshift dependency of the cluster halo
concentration parameter is crucial in obtaining an unbiased cluster mass
estimate and hence deriving the radial profiles of the enclosed total mass and
the gas pressure out to r200.
