END_OBJECT = TEXT END Please send comments by e-mail or U.S. mail to the PPI Node PDS Operator: This volume was produced for the Planetary Data System (PDS) at the Small Bodies node. The images, and associated metadata were supplied by Dr. Pablo Gutierrez-Marques, and Dr. Joachim Ripkin at the Max-Planck Institute for Solar System Research (MPS). The volume was assembled at the Dawn Science Center (DSC), by Steven Joy. Users are encouraged to provide feedback on any errors or omissions are found in the data or documentation.

All users are encouraged to verify the correctness of the data prior to submitting any publications or other work based on these data. Please report errors on this disk to the Small Bodies Node of the PDS through the ERRATA reporting procedures described above. The 'Known Discrepancies' section below lists know deviations from PDS archiving standards found on this volume. ============================================================================== Known Discrepancies ============================================================================== MD5_CHECKSUM.TXT - This file does not have the required PDS label. It contains a list of the MD5 checksum of every file on this volume and is provided for data assurance purposes. /BROWSE/.../*.LBL - These are the label files for the JPEG images provided in the in the BROWSE area of this archive volume. The PDS labels list JPEG as the ENCODING_TYPE. While 'JPEG' is not a valid standard value for ENCODING_TYPE, JPEG is an allowed format for browse products. /DATA/.../*.IMG and /DATA/.../*.LBL - The labels for the image files use the deprecated value "PC_REAL" for the SAMPLE_TYPE which is equivalent to "IEEE_REAL". /DATA/IMG/.../*.IMG and /DATA/FITS/.../*.LBL - The labels for the image files report incorrect values for CELESTIAL_NORTH_CLOCK_ANGLE (CNCA). The labels correctly compute the TWIST_ANGLE which can be used to compute the CNCA. CNCA = (180 - TWIST_ANGLE) mod 360. The CNCA value has been corrected in the GEOM_INDEX.TAB file. /DATA/IMG/.../*.IMG and /DATA/FITS/.../*.LBL - The labels for the image files report incorrect values for LOCAL_HOUR_ANGLE (LHA). The LHA value has been corrected in the GEOM_INDEX.TAB file. /DATA/FITS/*FIT - Not all FITS viewers display images in the same orientation. Some viewers display these images in an "upside down" orientation. /DATA/FITS/20180825_20180831/FC21A0100963_18241021249F1B.LBL and /DATA/IMG/20180825_20180831/FC21A0100963_18241021249F1B.IMG - The housekeeping data (including the spacecraft and instrument status information) is missing or corrupted for this image. Parameter values are mis-reported as zero or some equivalent value, which causes some values to fall outside of the valid range. The real parameter values should be similar to those for the preceding and subsequent images. It is unclear what affect the bad housekeeping values may have had on the processing, and therefore the quality of the image. /DATA/IMG/.../*.IMG, /DATA/FIT/.../*.LBL, /INDEX/GEOM_INDEX.TAB - A number of files were delivered by the FC team with no geometry information in the labels. Geometry information was generated for these files at the DSC and added to the FITS file label, and GEOM_INDEX.TAB files. The IMG file attached labels were not updated. Note that the geometry for the affected files was produced using a different method and will differ slightly from the values that would have been produced using the FC teams method. The variation in these values, however, is not significant enough to restrict their usefulness. The following files were affected: 20180609_20180614/FC21A0091402_18161165045F1I.LBL 20180609_20180614/FC21A0091768_18163231751F1I.LBL 20180615_20180620/FC21A0092311_18167084544F1K.LBL 20180615_20180620/FC21A0092496_18169142939F1K.LBL 20180615_20180620/FC21A0092505_18169143840F1K.LBL 20180615_20180620/FC21A0092515_18169144339F1K.LBL 20180615_20180620/FC21A0092526_18169144719F1K.LBL 20180615_20180620/FC21A0092536_18169144949F1K.LBL 20180615_20180620/FC21A0092554_18169145249F1K.LBL 20180615_20180620/FC21A0092641_18169150320F1K.LBL 20180615_20180620/FC21A0092661_18169150621F1K.LBL 20180615_20180620/FC21A0092671_18169150849F1K.LBL 20180621_20180625/FC21A0093041_18173005636F1J.LBL 20180621_20180625/FC21A0093225_18174041241F1J.LBL 20180621_20180625/FC21A0093409_18175072453F1J.LBL 20180625_20180701/FC21A0094373_18180232316F1D.LBL 20180702_20180708/FC21A0095357_18187184904F1E.LBL 20180715_20180722/FC21A0096178_18196195359F1C.LBL 20180715_20180722/FC21A0096191_18196195714F1C.LBL 20180722_20180728/FC21A0097287_18203152735F1C.LBL 20180722_20180728/FC21A0097300_18203153152F1C.LBL 20180722_20180728/FC21A0097315_18203153920F1C.LBL 20180722_20180728/FC21A0097882_18208043327F1C.LBL 20180729_20180804/FC21A0098021_18210104750F1C.LBL 20180729_20180804/FC21A0098038_18210110420F1C.LBL 20180811_20180817/FC21A0100071_18228063351F1D.LBL 20180811_20180817/FC21A0100072_18228063404F1D.LBL 20180811_20180817/FC21A0100073_18228063415F1D.LBL 20180825_20180831/FC21A0100977_18241021540F8B.LBL 20180825_20180831/FC21A0101123_18241213528F1B.LBL 20180825_20180831/FC21A0101124_18241213538F1B.LBL 20180825_20180831/FC21A0101125_18241213548F1B.LBL
