END_OBJECT = TEXT END Volume DWNCALFC1 Dawn Framing Camera 1 Calibration Image Archive ============================================================================== Brief Disk Description ============================================================================== This volume contains images from the Dawn Framing Camera 1 calibration image dataset. This dataset includes the image files to be used in the calibration of the raw data throughout the mission. The images in this data set represent the behaviour of each individual pixel with respect to dark current generation and pixel-to-pixel non-uniformity as a function of the filter. As these are elaborated image products, not obtained from a specific image acquisition, they do not have any ancillary data. This is version 2 of the FC1 Calibration volume. Version 1 contained an earlier version of the FLATs and composite darks through Ceres Approach. This version contains an updated version of the FLATs and composite darks for the Ceres extended mission activities where both cameras were used to acquire science images in the last two mapping orbits (XMO3 = CXG and XMO4 = CXO). All images are stored in the 'DATA' branch of the directory tree. In addition to the imagery, anciliary information is stored within the image headers. More information describing the image and volume format is contained in the Software Interface Specification (SIS). A copy of the SIS is provided in the /DOCUMENT/SIS directory of this volume. Users of these data are encouraged to acknowledge both the PDS and the principal investigators of the instruments whose data is used in analysis in all publications. ============================================================================== Volume Set Information ============================================================================== This volume is part of the Framing Camera 1 raw level-1A EDR images volume set. This volume set includes the following volumes: Volume ID Description ------------------------------------------------------- DWNXFC1_1A Dawn FC1 L1-A EDR cruise images DWNVFC1_1A Dawn FC1 L1-A EDR Vesta images DWNCFC1_1A Dawn FC1 L1-A EDR Ceres images DWNCALFC1 Dawn FC1 calibration images ============================================================================== File Formats ============================================================================== The image files on this volume are binary images, with an attached ASCII header (PDS label). The PDS label contains information describing spacecraft, target, and imaging parameters characterizing the attached image. A data set description, instrument description, and other PDS documents are in .CAT files in the /CATALOG directory. In more recent versions of the Microsoft Windows operating system the .CAT by default is reserved as 'Security Catalog.' The .CAT files contained in this volume are ASCII text files, and can be read by any form of text editor. To make Windows open files with this name extension as text files, do the following. In Windows Explorer, open the 'Tools' menu and select 'Folder Options'. Select the 'File Types' tab and select 'CAT' from the list. Press 'Change...' and then choose your prefered text editor or viewer. We do not know of any harmful effects this might have on the operating system or other programs, but do not guarantee it will be entirely safe to make this change. If problems occur, the change can be undone in the same 'File Types' window by changing the default application back to 'crypto shell extension'. Additional documentation is generally located in the DOCUMENT directory. ============================================================================== Errata ============================================================================== Every effort has been made to assure that the data and documentation are of the best possible quality. However, mistakes are inevitable. There is a file called ERRATA.TXT found at the root level of this volume which contains a list of known deficiencies or caveats associated with data on this volume at the time this volume was produced. ============================================================================== Volume Contents and Structure ============================================================================== This section describes the volume structure and naming conventions. Below is a tree diagram of the volume, followed by a description of the directory function and key files in each directory.

The images, and associated metadata were supplied by Dr. Pablo Gutierrez-Marques, and Thorsten Maue at the Max-Planck Institute for Solar System Research (MPS). The volume was assembled at the Dawn Science Center (DSC), by Joseph N. Mafi.
