Caution

The re-formatted volumes have NOT completed the peer review process. Please notify us of any problems or concerns you have with this version of the CIRS data.

Getting the Data You Want

  • Use OPUS, our versatile search engine to find and retrieve specific Cassini CIRS data products using a wide range of criteria.
    • Search results include data files, tables of associated metadata, and footprint diagrams for each observation. User selected data files can be bundled as tar.gz files for easy downloading.

  • The table below contains links to all of the available data volumes from the Saturn encounter re-formatted into fixed length data files. For information on the re-formatted data, see About Re-formatted Data.
  • Note: There is a time delay between the release of a new set of CIRS volumes and the generation of the corresponding reformatted versions. We will generate the latter and post them as quickly as possible.

    • Clicking on the Volume number will allow you to browse the volume.
    • To download an entire volume, right click on that volume's "Bundled" link in the second column.

      The bundled volumes are provided in .tar.gz format. For information on opening files of this type, click here.
    • Be aware that even with a 4:1 compression ratio, the Bundled versions can be on the order of 4GB and may take a few hours to download. Users are encouraged to download during the late night/early morning hours California time.

    • Clicking on Footprints will take you to a directory containing footprint diagrams of each CIRS observation. The RINDATA sub-directory contains diagrams of the ring footprints. The POIDATA sub-directory contains diagrams of the Saturn footprints. The APODSPEC/ISPM directory contains copies of one or the other - the ring footprints if the observation contains ring data, otherwise the Saturn footprint.

      For each observation, there are three foot print files: two jpg thumbnails and an epsf file. The suffix 200x200 indicates a small thumbnail of 200x200 pixels. The 650x650 suffix indicates a larger and more detailed diagram. The epsf files were used to generate the jpegs. They provide finer resolution than the jpegs.
