Cosmic Microwave Background Analysis Tools

The COMBAT collaboration exists to develop computational tools to facilitate the analysis of the massive datasets being gathered by a large number of cosmic microwave background anisotropy experiments. Our research is funded by NASA through its Advanced Information Systems Research Program . The COMBAT collaborators come from various disciplines including astrophysics, computer science and statistics.

Documentation and downloads for our various software tools
DASh The Davis Anisotropy Shortcut  is a fast method for calculating the angular power spectrum of the CMB given an inflationary cosmological model and estimating its likelihood with respect to a given dataset. 
EXCOP The EXctraction of COsmolgical Parameters software and database of inflationary cosmological models used to place constraints on six fundamental cosmological parameters given a CMB temperature anisotropy angular power spectrum and its covariance matrix.
FORECAST The FOREgrounds & CMB Anisotropy Simulation Tools software used to generate foreground and dipole maps and test experimental scanning strategies on them.
MADCAP The Microwave Anisotropy Dataset Computational Analysis Package used to make maps and noise correlation matrices from CMB timestream data, and extract the maximum likelihood angular power spectrum and its Fisher correlation matrix from these.
MADmap The Microwave Anisotropy Dataset map package is highly optimized parallel software that makes an approximate maximum likelihood map from CMB timestream data, and provides routines for many useful associated time/pixel domian data transformations.
MAPSIM The MAP SIMulator software generates temperature and polarization anisotropy maps as random Gaussian realizations of the associated CMB angular power spectra.
