These files contain the beam transforms and radial profiles of the ACT beam, which are appropriate for point source use with the ACT 150, 220, and 280 GHz maps of 2008-2010 data. More...
Catalog of extragalactic sources detected by the Atacama Cosmology Telescope at 150, 220 and 280 GHz for the 2008-2010 seasons along the southern surveys. More...
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.
The point source mask is a map, in FITS format, with the same footprint and World Coordinate System as the associated 148 GHz and 220 GHz data. More...
These files contain combined hit-count maps for each pixel of Atacama Cosmology Telescope (ACT) maps of the southern and equatorial fields, observed during the 2008-2010 seasons, in the 148 GHz and 217 GHz bands, and produced for the ACT data release in February 2014. More...
The ACT temperature power spectra are combined to estimated the CMB bandpowers, marginalized over foregrounds and SZ. Spectra are given for each region (ACT-E and ACT-S). The coadded spectra are also given. More...

These files contain the Atacama Cosmology Telescope (ACT) temperature maps of the southern and equatorial fields, observed during the 2008-2010 seasons, in the 148 GHz and 217 GHz bands, and produced for the ACT data release in February 2014. More...
A single tarball is supplied, containing the lensing likelihood and data for ACT. It is a simple chisq routine that takes in a theoretical deflection spectrum, and compares it to the ACT data file in the /data directory. More...
Oct-2013 Updated likelihood v2 released with updated ACT beams, and includes an improved binning of the spectra. As reported in the ACT papers, the effect on cosmological parameters is small, less than 0.1 sigma for the majority, up to a maximum of 0.2 sigma. This version also includes the newer Story et al 2012 SPT data at large scales as the default, instead of the Keisler et al 2012 SPT data. More...
Oct-2013 Updated likelihood v2p2 released with updated ACT beams, including the improved binning of the spectra used in v2p1. As reported in the ACT papers, the effect of this change on cosmological parameters is small, at the 0.1 sigma level. More...
The ACT temperature power spectra are computed at 148 GHz and 218 GHz. Three spectra are given for each region (ACT-E and ACT-S), for 148x148, 148x218, and 218x218. The coadded spectra are also given. More...

These two files represent the radial beam profile and the Fourier space window function of the ACT beam, appropriate for use with the ACT 148 GHz maps of 2008 data released with Dunner et al. More...
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...
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...
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...
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...
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...
