Abstract

ESA commissioned a Tiger Team to review the discrepancy between the prediction and measurement of the telescope back focal length. A team of 16 engineers and scientists collocated at ESA's Estec facility to review the test results in the context of the mission requirements and predictions for behavior of the telescope. Extensive analysis was performed on the random and systematic errors in the test results. Both room temperature and cryogenic test data was scrutinized. Error budgets, test results, and conclusions from the Tiger Team will be discussed.
