WMAP Software

WMAP online tools

• The effective frequency calculator returns the effective frequencies for each band given a set of spectral indices.

WMAP is distributing the following software packages:

• Cosmological Parameters Plotter is a tool that shows probability plots for various parameters derived from WMAP Markov Chains. [This has not been updated for the final WMAP release as yet and has therefore been disabled.]
• Likelihood Code, consisting of FORTRAN subroutines to compute the likelihood of an input theoretical power spectrum fit to the WMAP power spectra, using the correct Fisher matrix.
