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. Note this is version 2 of the gravity field, which has the corrected location of the Kait crater. During the development of higher-level data products for Dawn, the Gravity team discovered that the Gravity team and the imaging team were using different craters to define the coordinate system. Under concurrence from the Dawn project, the gravity team corrected the gravity field products to align with data products used by other teams. The corrected location of the Kait crater is a rotation of -0.064074 deg about the z-axis. The corresponding version 2 of the gravity field re-estimates the gravity field parameters, pole right ascension, declination, prime meridian, and rotation rate. The version 2 gravity field fixes the y-axis coordinate to align exactly with the Kait landmark crater. Details of the coordinate system are described in the corresponding labels for the DATA/SHADR and DATA/SHBDR data products. Because the gravity field was re-estimated in this new frame, the gravitational field parameters and pole frame are slightly different from the previous version. The change is large enough to affect the DATA/SHADR and DATA/SHBDR data products, which have been updated in the version 2 dataset but not large enough to affect the 1-degree resolution of the DATA/RSDMAP products, which remain unchanged.
