DATA_SET_DESCRIPTION |
Data Set Overview
=================
This dataset contains the results obtained from the Dust Impact
Detection System (DIDSY) flown aboard the GIOTTO spacecraft during
its extended mission to Comet P/Grigg-Skjellerup in 1992. The
measurements and analysis of the three impacts detected during close
approach are contained in text files. Calibration tables for the
sensors are included in this dataset.
Parameters
==========
The timing and masses of the impacting meteroid are tabulated within
the DOCUMENT file, 'didtext.doc'.
Processing
==========
See the 'didtext.doc' file for details of the data processing and
analysis.
For PDS ingest, the shield map files were each pulled out of the
original text file and formatted as separate PDS TABLE files, each
with its own label.
Data
====
The data set consists of four files:
didtext.doc An early draft of a paper published in April
1993 as a Letter to Nature. This file provides
a description of the experiment, presents the
results and includes a discussion of the data
analysis
did2map.tab These files contain the bumper shield maps for
did3map.tab each of the three sensors active during the
did4map.tab flyby. The maps indicate relative sensitivity
of each area on the shield compared to a direct
impact on the sensor.
Ancillary Data
==============
There is no ancillary data to this data set.
Coordinate System
=================
See the analysis section of the 'didtext.doc' file for a description
of the geometry of the impacts.
Software
========
Not applicable.
Media/Format
============
These data are available as part of the Giotto Extended Mission CDROM.

Confidence Level Overview
=========================
See the 'didtext.doc' file for a discussion of the analysis procedure
as well as the effects of the previous encounter with Comet P/Halley
on the DIDSY sensitivity at P/Grigg-Skjellerup.
Review
======
These data were reviewed for ingest into the PDS permanent archives in
December 1995.
