Likelihood Software This is the software used by the ACT collaboration to compute the likelihood of cosmological models, using the small-scale microwave power spectrum measured by ACT from the 2008 Southern sky survey. It is based on the WMAP likelihood software. More... 1 file, 4.6 MB TAR BALL
Chains These are MCMC chains run using the ACT likelihood software based on the small-scale microwave power spectrum measured from the 2008 Southern sky survey. More... 10 files, < 4.5 MB TAR BALL
Primordial Spectrum This is the software and chains used by the ACT collaboration in Hlozek et al 2011 [1105.4887]. It includes the modification to CAMB required to use a binned primordial power spectrum instead of a power law, and modifications to CosmoMC to sample these additional parameters. More... 2 files, < 336 KB TAR BALL
Beams The beam window functions for the ACT temperature power spectra are computed at 148 GHz and 218 GHz. They are obtained by transforming the beam profiles obtained from Saturn observations. More... 2 files, 451 kB each ASCII
Spectra The ACT temperature power spectra are computed at 148 GHz and 218 GHz. Three spectra are given, for 148x148, 148x218, and 218x218. More... 3 files, 4 kB each ASCII
Source Templates The angular power spectra shape due to clustered IR point sources as predicted by two different models (named Src-1, Src-2) are supplied for the 148 GHZ ACT frequency. More... 2 files, 221 kB each ASCII
SZ Templates The angular power spectra due to the Sunyaev-Zeldovich effect as predicted by four different models (named TBO-1, TBO-2, Battaglia, Shaw) are supplied for the 148 GHZ ACT frequency. More... 6 files, < 557 kB each ASCII

Likelihood Software This is the ACT lensing likelihood routine from Das et al 2011 (astro-ph/1103.2124), written in Fortran 90. More... 1 file, 111 KB TAR BALL
Chains This tarball includes 6 chains run for the lcdm+curvature model, with results reported in Sherwin et al 2011 (astro-ph/1103.0419), using WM AP 7-year data plus ACT lensing likelihood described in Das et al 2011 (astro-ph/1103.2124). More... 1 file, 3.3 MB TAR BALL

2008 SZ Clusters Catalog of 23 galaxy clusters detected by the Sunyaev-Zeldovich (SZ) effect in 455 square degrees of sky surveyed by ACT during 2008 at 148 GHz. The catalog gives the cluster names, positions, redshifts, signal-to-noise, and measured SZ signal. SZ and optical images of each cluster are also included. N/A ASCII
Point Source Catalog This is a catalog of point sources detected in a 148 GHz data collected by ACT . More... 1 files, 20 kB ASCII
