END_OBJECT = TEXT END Volume DWNVFC2_1B Dawn Framing Camera 2 Calibrated Level-1B Vesta Archive ============================================================================== Brief Disk Description ============================================================================== This volume contains calibrated level-1B (RDR) Framing Camera 2 images from all of the Dawn Vesta encounter phases (Approach, Survey, transfer to HAMO, HAMO, transfer to LAMO, LAMO, transfer to HAMO2, HAMO-2, and transfer to Ceres). NOTE: Reading the Science Plan (located in the /DOCUMENTS/SCIENCE_PLAN directory) is critical to the understanding of the Vesta observations and science objectives. Other critical documentation in the DOCUMENT directory include the volume SIS and calibration procedure. The images in this dataset have been radiometrically calibrated by means of fully reversible procedures, transforming the value of the pixels from digital units to applicable engineering units without modification of the geometry. All images are stored in the 'DATA' branch of the directory tree. The data are provided in both PDS Image (IMG) and FITS formats. Anciliary information is stored within the image headers for the IMG, and in detached PDS labels for the FITS files. Calibration files needed for further processing are archived as part of the DAWN-CAL-FC2-2-EDR-CALIB-IMAGES-V1.0 data set. 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. SPICE kernels are archived by the NAIF Node of the PDS. 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. ============================================================================== Image File Naming Convention ============================================================================== Convention: FCxllimageid_yydddhhmmssFnz.IMG Example: FC21B0003923_11223174143F1A.IMG Where: FCx indicates the instrument (FC2) ll indicates the data processing level (1B) IMAGEID image id (7 characters, zero-padded - 0003923) yyddd indicates the image acquisition year/doy (11223) hhmmss indicates the image acquisition SCET (UTC - 174143) Fn n indicates the filter number used in capturing the image (F1) z indicates the data file version (A-Z - A) Note that in instances (like spacecraft safings, etc.) where the Framing Camera powered off without being able to store the last image number used, images were generated with duplicate image numbers. In order to eliminate the duplication 3,000,000 was added to the image number in the ground processing (e.g. a duplicate image number 0014325 would become image number 3014325). As a result consecutive images may not always have consecutive image numbers. ============================================================================== Volume Set Information ============================================================================== This volume is part of the Framing Camera 2 calibrated level-1B RDR images volume set.

Approach/OpNav #011: All images from were lost due to a spacecraft safing. [2] Approach/Moon Search: Images from the three Moon Search observations (MoonSrch #1, #2, and #3), have been combined into a single data directory: "2011190_MOON_SEARCH". [3] RC3/RC3B: 15/16 images (respectively) in each of these observations were 0 ms exposures. While these images are present in the L-1A data set, they have not been included in the L-1B data set. [4] HAMO/Cycle 1: Due to an overflow of the camera the number of images in camera memory 104 images in orbit 9, and 68 in orbit 10 were transmitted raw format. The file size, and number image object defined in these images is different from other images. [5] HAMO/Cycle 2: All FC images from orbit 1 were lost due to a delay in uploading science command sequences. [6] Transfer to LAMO: OpNav #002 and #003 were cancelled as the spacecraft was on the night side of Vesta at the scheduled observation time. [7] LAMO/Cycle 1: 131 images were lost due to a spacecraft safing. [8] LAMO/Cycle 6: All images were lost due a spacecraft safing. [9] LAMO/Cycle 11: 40 images were lost due to a spacecraft safing. [10] LAMO/Cycle 13: 252 images were lost due to a spacecraft safing. ============================================================================== File Formats ============================================================================== The image files on this volume are binary images. IMG files have an attached ASCII header (PDS label). The FITS versions have a detached 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.
