DAWN FC1 RAW (EDR) CERES IMAGES V1.0

Abstract ======== This dataset contains raw Framing Camera 1 (FC1) images sometimes called level-1a or EDR data. It includes images from the Dawn Ceres eXtended Mission Orbit 3 (XMO3, aka Ceres Extended GRaND - CXG) phase on 2017-02-19 and the Ceres eXtended Mission Orbit 4 (XMO4, aka Ceres Extended Opposition - CXO) phase on 2017-04-29. FC1 is one of two identical units flying on Dawn spacecraft. It was designated as the backup system to be used only in the event of a failure of the primary system, FC2. Prior to the Ceres extended mission, FC1 had only been used for in-flight calibration and to periodically exercise its various mechanisms (door, filter wheel, etc.). This is the only science dataset generated by FC1.
