The calibration of the Cassini Imaging Science Subsystem (ISS) and the resulting report is the product of the efforts of a dedicated team of people who made up the ISS Development Team which was led by Tom Livermore, and later by Bill Harris.

The subsystem level calibration testing of the flight cameras extended over a period of 8-months. Accordingly, critical to the calibration task were the schedule and resource planning (Bill Harris), test requirements development (Cindy Kahn and Bob West), test procedures (many), and test equipment development (David Brown). Also critical to the calibration task were the many members of the development team who came in at all hours to work and/or support the shifts providing 24-hour test coverage.

Needless to say, an extensive amount of data was taken during the 8-month period, which was filtered through and largely evaluated by Charles Avis of the Multi-Imaging Processing Laboratory of JPL. It should be noted that a significant amount of this report is the result of the efforts of Charles Avis. Charlie's analysis, close scrutiny, and thoroughness were critical elements in the completion and quality of this report.

In addition to Charles Avis' contributions to this report, there were many other contributing authors that I would like to mention and express my gratitude towards : Mark Schwochert, Lloyd Adams, Gary Yagi, Cindy Kahn, Robert West, Ed Motts, Alfred McEwen, David O'brien, and Peter Thomas. Other referenced reports included the work performed by Geoff James, Brad Wallis, Ken Manatt, and the Space Dynamics Laboratory of the Utah State University. Their expertise and input enabled a more complete and thorough report.

The efforts of ISS Science Team Leader, Carolyn Porco, to ensure the science team input of the analysis of the calibration data is very much appreciated. Recognition must be given to the following science team members who's reports are included as an appendix (hardcopy version) : Kevin Beurle, Carl D. Murray, Peter Thomas, and Vance Haemmerle. The input for the lossy compression calibration test definition and data analysis provided by Steve Squyres must also be recognized, as well as the lossy compression data analysis and report contributions provided by David O'brien. Other science team member's contributions are noted above as contributing authors.

A special thanks must go to Bob West for his guidance and feedback throughout the process of writing this report, as well as for his analytical and report contributions.

Additionally, the knowledge and experience provided by Cindy Kahn has been greatly appreciated. As always, Cindy was able to either provide the answers or point me in the right direction.

Other significant contributors in the areas of component level testing and/or calibration equipment test development include Dave Thiessen, Darryl Day, Wayne Hartford, Dan Preston, Mark Schwochert, Brad Wallis, Ken Manatt, Larry Steimle, and Dick Zatenson.

Acknowledgment must be given to David Brown, who was the former ISS Calibration Engineer from development through flight calibration testing. Dave put a lot of effort into taking care of the details of the calibration task : planning and designing test equipment, calibrating test equipment, and defining calibration procedures.

Also to be recognized is the ISS Calibration Report Web Page Designer, Kalee Perrin. Kalee created a web page that is easy to navigate, considering the large amount of information that had to be presented, and used her ingenuity on determining the best way to present the information. Also to be noted is the artistic components that she added that most certainly would have been lacking if I attempted to do this activity on my own.

Critical to the completion of this report was the technical support provided by James Gerhard who had an endless base of tools and knowledge to draw upon. Many thanks for making the job much easier to complete.

For the many people that I did not specifically name, but who contributed directly and indirectly to this report - thank you.
