Bandpowers Update: Dec 2017
The data files and updated CMBlikes.f90 file necessary to incorporate the SPT likelihood in current versions of CosmoMC can be found here in a gzipped tarball. The included README has instructions.
Bandpowers Update: Aug 2017
Files with the missing beam terms and revised calibration treatment can be found here in a gzipped tarball. The included README has instructions.
Bandpowers Update: Jun 11, 2014
Files compatible with the latest (May 2014) version of cosmomc can be downloaded here in a gzipped tarball. These files can be used without recompiling cosmomc. The included README has instructions.
The bandpowers, covariances and window functions are here in a gzipped tarball.
An alternative form of the newdat file with the calibration uncertainty moved from the covariance matrix to line 10 can be found here.
These are the SPT 150 GHz Bandpowers from 2008 to 2011 observations. The bandpowers cover the multipole range 650 < ell < 3000 in bins of delta-ell = 50.
Note that these bandpowers include power from foreground components such as SZ and point sources. The contributions from these components must be accounted for in order to properly analyze the SPT bandpowers, as described in Section 6.1 of Story et al. For convenience we give the ell-space templates for these components (in "units" of D_ell=C_ell*ell*(ell+1)/2PI and normalized to equal 1 at ell=3000):
The prior on the amplitude of the SZ (tSZ+kSZ) component (template) is D3000 = 5.5 +/- 3.0 uK^2.
The prior on the amplitude of the Poisson point source component (template) is D3000 = 19.3 +/- 3.5 uK^2.
The prior on the amplitude of the clustered point source component (template) is D3000 = 5.0 +/- 2.5 uK^2.
An alternative form with the foreground priors placed in the newdat file is here in a gzipped tarball. Note that chains in the paper did not use this form, and that the implemented prior no longer gaurantees each of the three foreground terms is positive definite. We expect the latter effect to be small. This newdat file may be simpler to use since it is compatible with an unmodified version of cosmomc - there is no requirement to add the three SPT foreground terms to cosmomc.
The foreground amplitudes are also required to be positive.
A text file with the bandpowers for plotting can be found here. Each row is one ell-bin. The columns are (1) ell_center (2) bandpower for 150x150, (3) bandpower uncertainty for 150x150. Each ell bin has the same width: 50.
A raw dump of compressed (tar.gz) chains is available. Each tar file corresponds to a single dataset/cosmological model combination. These files can be browsed here.
Update: Aug 2017
The SPT collaboration has uploaded a select set of key chains run with the revised likelihood. These files can be browsed here.
