The data made available through this page has been updated. The most recent version of this data may be accessed through https://lambda.gsfc.nasa.gov/product/wmap/current/
This is the software used by the WMAP team to compute Fisher and Master matrices, and to compute the likelihoods of various models.
This software is written in Fortran 90; it has been tested with the SGI MIPSpro, NAG, and Intel Fortran 90 compilers. It requires the following libraries:
The full tarball is 339.3MB in size, and decompresses to 594.4MB; the bulk of this space are the required data files. Please bear this in mind as you download this software. For convenience the software portion of this tarball is made available; no data is supplied, limiting its usefulness, but it is MUCH smaller.
To build it, you should edit the Makefile to support your current environment; the provided Makefile shows several possible configurations; these configurations have been tested.
make # Builds the likelihood software library. make check # Builds and the test program, and diff's the output # to the correct results.
Output differences of ~0.001 between platforms are normal.
See "CHANGES" for more details describing each release.

The tarball contains a data subdirectory that contains various input files. These input files are either ASCII text files containing columns of data, or FITS files containing binary data.
The tarball also contains the following files:
