Please send comments by e-mail or U.S. mail to the Imaging Node PDS Operator: PDS - Flagstaff Imaging Node United states Geological Survey 2255 North Gemini Drive Flagstaff, AZ 86001 Electronic mail address: pdsmgr@usgs.gov An updated version of this file is maintained online at the Imaging Node of the Planetary Data System. The online errata list can be found within Mercury Messenger related content on the World Wide Web at http://pdsimg.jpl.nasa.gov/ This file, ERRATA.TXT, contains release notes and errata concerning the MESSENGER MDIS HIW archive. During the course of the MESSENGER mission the MDIS science team may update previously released data products or documentation; for example, updates may occur due to changes in calibration data or procedures. Updates will be reported in this file and be distinguished in the archive by an increase in the version number contained in the file name. Older versions of data and documentation will not be retained in the archive. Section A of this file contains an entry for each MESSENGER release with general information about the contents of the release, in order from newest to oldest. Updates to previously released files are reported in these entries, along with any known errata. Section B of this file contains general notes, if any, concerning the archive as a whole. ******** SECTION A ******** RELEASE NUMBER: 16 RELEASE DATE: 2017-05-12 DATA COVERAGE: 2011-03-29 to 2015-04-30 PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS HIW BROWSE IMAGES PRODUCT TYPES UPDATED FOR THIS ARCHIVE: MDIS HIW REASON FOR UPDATES: Product reprocessing and addition of browse images Version 2 HIW files (e.g., MDIS_HIW_256PPD_H15SP2) supplant the previously archived version 1 files with improved stacking algorithms and refined manual image selection or exclusion. The optimum solar incidence angle sought for image stacking priority changed from 78 degrees to 86 degrees. PNG format browse images of the version 2 products are provided in the EXTRAS/BROWSE/H/ directories. These are accompanied by GDAL-compatible XML files containing associated map projection metadata. Shapefiles in the EXTRAS/IMG_FOOTPRINTS/ directory have been revised. --------------------------------------------------------------------------- RELEASE NUMBER: 15 RELEASE DATE: 2016-05-06 DATA COVERAGE: 2011-03-29 to 2015-04-30 PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS HIW PRODUCT TYPES UPDATED FOR THIS ARCHIVE: MDIS HIW REASON FOR UPDATES: Product finalization This release includes a complete redelivery of the HIW basemap that has been reprocessed using the USGS global DEM and final SPICE parameters (including improved "smithed" CKs produced as part of the USGS global DEM generation), all final calibrations and corrections, as applicable with the following exceptions: None. Shapefiles that record the MDIS image coverage area of Mercury during the orbital mission have been added to the EXTRAS directory. Please see EXTRINFO.TXT for more information. --------------------------------------------------------------------------- RELEASE NUMBER: 13 RELEASE DATE: 2015-03-06 DATA COVERAGE: 2011-03-29 to 2014-03-17 PRODUCT TYPES RELEASED FOR THIS ARCHIVE: MDIS HIW PRODUCT TYPES UPDATED FOR THIS ARCHIVE: NONE REASON FOR UPDATES: N/A 1.
