The full tarball is 987.67MB in size, and decompresses to 1705.86MB; the bulk of this space are the required data files. Please bear this in mind as you download this software.
Due to the size of the tarball, we recommend that you use a utility such as wget to download it. The wget command would be:
wget 'http://lambda.gsfc.nasa.gov/data/map/dr4/dcp/wmap_likelihood_full_v4.tar.gz'
