Calibrated Images

  • Calibrated versions of each Cassini ISS image from the Saturn encounter phase can be downloaded from OPUS search results.

  • You also can access calibrated versions of each Cassini ISS image from the Saturn encounter phase, organized by volume number, from the the table on the Accessing Data tab.

Calibration Software

Calibration software is available on the COISS_0011 volume. The entire volume can be downloaded by right clicking here (tar.gz format).

For discussions of available ISS calibration and image analysis software, see ISS Software).

Calibration Files

The calibration documents and pre-flight ground calibration images are contained on volumes COISS_0001-0010.

Documentation

Detailed information on the various calibration tests is contained in the complete set of documents found in the document directory on each volume. These include:

  • The ISS Calibration Report: report.

  • The in-flight calibration plan: pdf or TeX.

  • Calibration theoretical basis report: pdf or TeX.

  • CISSCAL calibration software manual: pdf or TeX.

Calibration Data

The calibration test data are found within the data directory tree on volumes COISS_0001-0010.

On each Volume, separate subdirectories contain data for the narrow-angle and wide-angle cameras (NACFM and WACFM respectively). Within each of these directories, subdirectories are named to indicate which test the enclosed data supports.

The table below indicates where to find calibration data for a particular

camera and test.

  • Clicking on the VOLUME_ID will allow you to browse the volume.

  • To download an entire volume, right click on that volume’s “Bundle” link in the second row of each section.

The bundled volumes are provided in tar.gz format.
