  Studies of the diffuse X-ray emitting gas in galaxy clusters have provided
powerful constraints on cosmological parameters and insights into plasma
astrophysics. However, measurements of the faint cluster outskirts have become
possible only over the last few years. Here, we present results from Suzaku
observations of the Perseus Cluster, which provide our best measurements of the
thermodynamic properties of the ICM at large radii to date. In particular, we
focus on the details of the data analysis procedure and discuss the evidence
for a clumpy distribution of the gas in the outskirts, which is important for
understanding the physics of the ongoing growth of clusters from the
surrounding cosmic web.
