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 finite element models, optical models, and supporting data to validate the methodology of prediction and verify the results. The team used several modeling techniques including: paraxial models, first order thermal expansion models, full system and metrology raytracing, deterministic and stochastic finite element models. The techniques, assumptions, and results will be discussed.
