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 team's likelihood software.
This software is written in Fortran 90. It requires the following library:
A single tarball is supplied, containing the 148-GHz-only likelihood and data. This is described in Section 2.1 of Dunkley et al astro-ph/1009.0866, and is referred to in the paper as the '148-only' likelihood. See the readme.txt file for more information.
To build, modify the Makefile to reflect your system's environment. Then
> make # Compiles the likelihood software and builds a test program. > ./test # Runs the test program.
