摘要：

Large Sunyaev- Zel'dovich - selected galaxy cluster surveys are beginning imminently. We compare the dependence of the galaxy cluster angular power spectrum on cosmological parameters, different modeling assumptions, and statistical observational errors. We quantify the degeneracies between theoretical assumptions such as the mass function and cosmological parameters such as sigma(8). We also identify a rough scaling behavior of this angular power spectrum with sigma(8) alone.
