title = "Ground and In-Flight Calibration of the OSIRIS-REx Camera Suite",
abstract = "The OSIRIS-REx Camera Suite (OCAMS) onboard the OSIRIS-REx spacecraft is used to study the shape and surface of the mission{\textquoteright}s target, asteroid (101955) Bennu, in support of the selection of a sampling site. We present calibration methods and results for the three OCAMS cameras—MapCam, PolyCam, and SamCam—using data from pre-flight and in-flight calibration campaigns. Pre-flight calibrations established a baseline for a variety of camera properties, including bias and dark behavior, flat fields, stray light, and radiometric calibration. In-flight activities updated these calibrations where possible, allowing us to confidently measure Bennu{\textquoteright}s surface. Accurate calibration is critical not only for establishing a global understanding of Bennu, but also for enabling analyses of potential sampling locations and for providing scientific context for the returned sample.",

note = "Funding Information: This material is based upon work supported by NASA under Contract NNM10AA11C issued through the New Frontiers Program. We thank the Japan Aerospace Exploration Agency (JAXA) and the JAXA SELENE/Kaguya mission for making the MI data publicly available. The ground test planning, execution, and data analysis was supported by the entire OCAMS team, and in particular the testing and systems engineering teams. Flight activities are dependent on the spacecraft team at Lockheed Martin and operations and planning teams at the University of Arizona. The authors thank all who work on OCAMS and OSIRIS-REx for their continuing efforts. ",
