The whole contents of the Gaia source catalog can be downloaded as separate 5231 fits files or pipe-separated-value (psv) files. Total file size is 342GB for fits files or 226GB for gzipped psv files.
$ wget --content-disposition -i gaiadr1-gaia_source-fits-url.dat
The column names of psv files are:
