Users are encouraged to provide comments back to the PPI Node of the PDS if errors or omissions are found either in data or in documentation. Please send comments by e-mail or U.S. mail to PDS Operator as defined at the end of this document. For questions regarding data content, processing, or quality, please see the contact information at the end of this document. ============================================================================= Brief Volume Description ============================================================================= This volume contains NEAR MAG data from the EROS/ORBIT phase of the Near Earth Asteroid Rendezvous (NEAR) mission. The primary documentation for this volume is located in the CATALOG directory. The data are described by the file /CATALOG/NEAR_RDR_EROSORBIT_DS.CAT on this volume. The mission phases are described in /CATALOG/NEAR_MISSION.CAT. All data files are stored in the /DATA branch of the directory tree. Each data file is located in the /DATA directory or in a subdirectory beneath it. All data are stored in tables in FITS format, with attached FITS headers. All data files on this volume are described by detached PDS labels (*.LBL). Each detached label file contains information about the corresponding data file, including descriptions of the columns if the data file is tabular. Metadata are stored as text files with the data. Information on the particular form of metadata used in the PDS catalog can be found in the CATALOG directory. ============================================================================= Volume Set Information ============================================================================= NEAR data sets contain data from only one instrument and one mission phase. Mission phases for data sets are defined in the table below. Each data set contains the data from a range of days, along with supporting documentation for those data. Mission Phase Parameters (Planned Values; Feb. 2000) -------------------------------------------------------------------- Segment Start (Year, End (Year, Length Phase Name (Phase Abbrv) Day Of Year) Day Of Year) (Days) -------------------------------------------------------------------- CRUISE1 CRU1 1996-051 1997-175 491 MATHILDE MATH 1997-176 1997-178 3 CRUISE2 CRU2 1997-179 1998-022 209 EARTH ERTH 1998-023 1998-026 4 CRUISE3 CRU3 1998-027 1998-356 330 EROS/FLY/BY ERFB 1998-357 1998-357 1 CRUISE4 CRU4 1998-358 2000-010 383 EROS/ORBIT EROS 2000-011 2001-043 399 EROS/SURFACE ERSF 2001-044 2001-059 16 -------------------------------------------------------------------- The NEAR Science Data Center (SDC) archives NEAR uncalibrated science data at the Small Bodies Node (SBN) of the Planetary Data System (PDS), as specified in the NEAR Project Archive Generation, Validation and Transfer Plan (February 1998). The February 1998 Plan document is in the DOCUMENT subdirectory of this data set, in the file PDSARCHIVEPLAN, in text (.TXT) and rich text (.RTF) formats. The included plan is dated February 1998. It is expected to be updated with final definitions of higher level products. The revised plan will be included in later time periods of this data set. ============================================================================= File Formats ============================================================================= The data files on this volume are in FITS format. All data files are described by detached PDS labels. A detached label file has the same name as the data file that it describes, but with the extension .LBL. For example, the file MAG01050.FIT would be accompanied by the detached label file MAG01050.LBL in the same directory. File names within this archive conform with the ISO-9660 Level 2 standard. * All PDS labels on this volume are located in the same directory as the file they describe so this construct is not used here. In cases where many files of the same format or structure are present, the structure description component is detached from the primary label. This minimizes repeating information which does not vary from file to file. In these cases, a format file (.FMT) contains the file structure information and the base label (.LBL) describes the parameters which generally do vary from file to file (number of records, file name, start/stop time, etc.). When a format file is used within the PDS label, the syntax is: ^STRUCTURE = filename Example: ^STRUCTURE = "EDRHDR.FMT" Syntactically, the contents of the format file can be inserted directly into the base label such that the entire file contents replace the single line ^STRUCTURE = filename. ============================================================================= Errata ============================================================================= 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 published. If you find an error on this volume, please report the error to the PDS Operator at the PPI Node of the PDS. Email pds_operator@igpp.ucla.edu Telephone (310) 206-6073 U.S. Mail PDS Operator c/o Dr. Raymond Walker UCLA - IGPP Los Angeles, CA 90095-1567 Only through support and feedback of the users of these data can an effective errata list be maintained. ============================================================================= Software ============================================================================= This volume includes a version of the Splash software, which allows the user of the volume to make plots of the data. The Splash program is in the directory EXTRAS/SPLASH. The subdirectories of EXTRAS/SPLASH contain files which, when opened with Splash, allow the user to plot much of the data on the volume. The Splash software runs only on Windows PC platforms, and must be installed on the user's hard drive before it will run. The Splash software was developed at the Institute of Geophysics and Planetary Physics at the University of California, Los Angeles. The software is protected by copyright; please refer to the notices in the software. Users are responsible for respecting all copyrights. ============================================================================= Volume Contents and Structure ============================================================================= This section describes the volume structure and naming conventions.
