DAWN FC1 CALIBRATED CERES IMAGES V1.0

Abstract ======== This dataset contains calibrated Framing Camera 1 (FC1) images sometimes called level-1b or reduced data. It includes images from the Dawn Ceres eXtended Mission 1 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. In addition, there are images from eXtended Mission 2 (XM2), orbits XMO6 (C2I - intermediate), and XMO7 (C2E - elliptical) as well as some checkout and end-of-mission star calibration images. FC1 is one of two identical units flying on the 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.
