This dataset contains GIOTTO Ion Mass Spectrometer (High Intensity) observations of 1P/Halley. Every effort has been made to insure that the data are of the best quality available. However, the PDS and the Planetary Plasma Interactions (PPI) Node in particular, assume no liability for this volume or its contents. Users are encouraged to verify the 'correctness' of the data prior to submitting any publications or other work based on these data. Re-organized International Halley Watch (IHW) Data Sets ======================================================= The original IHW volumes HAL_0025 and HAL_0026 contain data from several spacecraft that flew by comets Halley and Giacobini-Zinner, over 40 data sets in all on the 2 volumes. The data were sorted into subdirectories by spacecraft and instrument, with shared supporting directories. The data were also archived under a fairly early form of the PDS Standards, and formatted to an equally early form of the FITS table standard, where appropriate, occasionally producing some arcane formats for the modern user - including PDS labels with deprecated terminology and FITS files that sometimmes have their header segments separated from their data segments. The reorganization effort sought to separate the data files constituting the unique data sets into a more contemporary, single-data-set-per-volume format for ease of access and distribution. The data have been sorted into a subdirectory hierarchy based on observation date, unless the number of data files was small enough that this seemed more disruptive than helpful, in which case all the observations are located directly in the DATA/ subdirectory. Although the original disks included executable files for some simple utilities, these have been omitted from the reorganized data. No modern system would run the executables, and in most cases no source code was provided. For those rare cases where source was provided, it has been relocated to a relevant support directory where its principal value is as documentation. Note that PDS does not and will not support this code. - A.C.Raugh, 2011-05-25 Brief Volume Description ======================== This data set is organized into 5 principal sub-directories: CATALOG PDS catalog templates describing the mission, spacecraft, instrument, and data set DATA science data DOCUMENT documents describing the mission, instrument and/or dataset INDEX index of all user files contained on this volume GEOMETRY contains ephemeris information and related files Contacts ======== The person most directly responsible for the construction and release of this volume is Mr. Steven Joy. He was the PPI Node Data Administrator at the time this volume was created and understands as much about the structure and data organization as anyone. Other PPI personnel who may be aware of about issues related to this volume include Dr. Raymond Walker, the PDS/PPI node manager.

Note that not all of the files mentioned below are a part of the current data set volume. ***** File AAREADME.TXT This compact disk (CD-ROM) is one of a 2-disk set containing data obtained through the efforts of the International Halley Watch (IHW) Disciplines and the Lead Center. These volumes are devoted to data returned by the intercept spacecraft for comet Halley and the International Cometary Explorer (ICE) for comet Giacobini-Zinner as listed below: COMET DATSASET NAMES DISK HALLEY GIOTTO DUST IMPACT DETECTOR SYSTEM 25 GIOTTO RADIO SCIENCE EXPERIMENT 25 GIOTTO HALLEY MULTICOLOR CAMERA 25 GIOTTO ION MASS SPECTROMETER HIGH ENERGY RANGE 25 GIOTTO ION MASS SPECTROMETER HIGH INTENSITY 25 GIOTTO JOHSTONE PARTICLE ANALZER MERGED 25 GIOTTO MAGNETOMETER 8 SECOND DATA 25 GIOTTO OPTICAL PROBE EXPERIMENT 25 GIOTTO PARTICLE IMPACT ANALYZER DUST MASS 25 SAKIGAKE INTERPLANETRAY MAGNETIC FIELD 25 SAKIGAKE SOLAR WIND EXPERIMENT 25 SUISEI ENERGY SPECTRUM PARTICLE 25 VEGA1 DUST PARTICLE COUNTER MASS ANALYSER 26 VEGA1 INFRARED SPECTROMETER IMAGING CHANNEL 26 VEGA1 INFRARED SPECTROMETER HIGH RESOLUTION CHANNEL 26 VEGA1 PLASMAG-1 PLASMA ENERGY ANALYSER 26 VEGA1 PUMA DUST MASS SPECTRA 26 VEGA1 PUMA DUST MASS SPECTRA-MODAL 26 VEGA1 DUST PARTICLE IMPACT PLASMA DETECTOR 26 VEGA1 DUST PARTICLE IMPACT DETECTOR 26 VEGA1 TUNDE-M ENERGETIC PARTICLE ANALYSER 26 VEGA1 TELEVISION SYSTEM 26 VEGA1 TELEVISION SYSTEM-KFKI 26 VEGA2 DUST PARTICLE COUNTER MASS ANALYSER 26 VEGA2 PLASMAG-1 PLASMA ENERGY ANALYSER 26 VEGA2 PUMA DUST MASS SPECTRA 26 VEGA2 PUMA DUST MASS SPECTRA-MODAL 26 VEGA2 DUST PARTICLE IMPACT PLASMA DETECTOR 26 VEGA2 DUST PARTICLE IMPACT DETECTOR 26 VEGA2 TELEVISION SYSTEM 26 VEGA2 TELEVISION SYSTEM-KFKI 26 VEGA2 TELEVISION SYSTEM-IKF 26 GIACOBINI-ZINNER ICE ENERGETIC PARTICLE ANISOTROPY SPECTROMETER 26 ICE MAGNETOMETER 26 ICE PLASMA WAVE ELECTRIC FIELD 26 ICE PLASMA WAVE MAGNETIC FIELD 26 ICE RADIO WAVE 26 ICE SOLAR WIND PLASMA ELECTRON ANALYSER 26 These are the last CD-ROMs of the Comet Halley archive, volumes 25 and 26. In addition to the data themselves, the disks contain a wide variety of supporting files and tools for the Archive user; the major categories are documentation, ephemeris information, searchable tables and indices, and software (source code as well as executable modules). These have been organized into three principal directories one level below the root: DOCUMENT INDEX, and SOFTWARE. It is suggested that the Archive user review the document files listed below before roaming through the multi-level data directories. There is one file, CDSTRUCT, in the DOCUMENT directory that is a complete listing of files (with path) organized by Logical Block Number. /DOCUMENT/VOLINFO.TXT Brief guide to use of disks /DOCUMENT/CDTREE.TXT Schematic, annotated layout of disk /DOCUMENT/ESA_1066/*.TXT A brief description of each mission /DOCUMENT/ESA_1077/*.TXT A brief description of GIOTTO experiments The time period covered for this volume (25) is March 03-14, 1986. All of the text files on this disk have fixed length records padded to 80 or 132 bytes per record. The last two characters of each record are a carriage return and line feed. This has been done to files with the following extensions (*.DOC, *.LBL, and *.TXT).
