title = "Ground-based calibration of the TAUVEX flight model",
abstract = "We describe in detail the procedures used for the ground testing and calibration of the flight model of the TAUVEX space telescope. We present the measurements done for this purpose, the various assumptions adopted during the ground calibration process, the results obtained, and provide a first approximation to the real performance of the experiment. The results of the ground-based calibration are that the system complies with the predicted performance in all aspects except for the total throughput, which is a factor of ~5 smaller than expected. However, the instrument sensitivity measurement is highly uncertain due to known limitations of the available equipment and a more accurate calibration will be performed in orbit.",

note = "Funding Information: The TAUVEX space telescope array, constructed for Tel Aviv University with funding from the Israel Space Agency (ISA, at the Ministry of Science, Culture, and Sport), Elbit Systems Electro-Optics ELOP Ltd., and Tel Aviv University, was conceived as a means to provide wide-field astronomical imaging of the UV sky. It consists of three co-aligned 20-cm aperture telescopes, T1, T2, and T3, mounted on a single bezel. The telescopes image the same ∼one-degree field of view (FOV) in the vacuum UV using position-sensitive, photon-counting detectors. Descriptions of the previous incarnation of TAUVEX were presented by Brosch et al. (1992), Topaz et al. (1993a, 1993b) and Brosch et al. (1992, 1994). Funding Information: Acknowledgements TAUVEX is supported by the Israel Space Agency (ISA), the Ministry of Science, Technology and Sport. EA, NB, and HN acknowledge continued support for this project from the Austrian Friends of Tel Aviv University. We are grateful to Prof. Amos Breskin and his group at the Weizmann Institute for help throughout the project. An anonymous referee is acknowledged for constructive remarks.",
