Recommended download procedure for '.fits' or '.tar.gz' files: right click on the file name and save.

Select a galaxy from the list below. For each galaxy, 32 files are available. Files with names beginning 'IM' contain the high resolution maps, while those which begin 'RS' contain reference images of simulated point sources. The third character in the filename indicates the wavelength band: '1' for 10 microns, '2' for 25 microns, '3' for 60 microns, '4' for 100 microns. The final 2-digit number in the filename gives the number of processing iterations -- 1, 5, 10 or 20.
