South Pole Telescope (SPT)

Likelihood 2012 Code

Likelihood code

The new bandpowers and foreground templates can be used with the Keisler et al. 2011 likelihood code for cosmomc. These modifications to cosmomc are not necessary if the newdat file including the foreground priors is used. The SPT-CL cluster likelihood used in some chains can be found here.

Keisler et al. 2011 likelihood code

We provide a version of cosmoMC + CAMB files that have been modified to interface with the CMB data presented in the SPT paper, "A Measurement of the Damping Tail of the Cosmic Microwave Background Power Spectrum with the South Pole Telescope", Keisler et al, 2011 ("K11"). The code will automatically marginalize over the three foreground components described in K11 and allow the user to explore constraints on the lensing amplitude, the primordial helium abundance, and the effective number of relativistic species.

This is not the exact likelihood code used in K11, but the differences in parameter constraints are not statistically significant. We provide only those cosmoMC/CAMB files that were modified. Please read the README before using.
