Deep Impact 9P/Tempel Cruise - Raw Navigation Images from the Medium-Resolution Visible CCD (MRI)

Status: Archived

This data set contains version 1.1 of raw calibration and test images acquired by the Deep Impact Medium Resolution Instrument Visible CCD during the cruise phase of the mission. These observations were used for optical and autonomous navigation (NAV) of the flyby spacecraft. These data were collected from 14 January to 25 April 2005. Test images of comet 9P/Tempel 1 were acquired on 25 April.

In this version 1.1 of the data set, the values for the INTEGRATION_DURATION keyword in the PDS data labels were corrected. This revised data set supersedes version 1.0.

The entire data set has been gathered into one physical volume (an ISO image) for downloading. It includes includes all catalog, index, and suport files for the data set.

• DIMVNV_1001 - data for January 14-April 25/DOY 014-115   (1.6 GB ISO file)
• Catalog, index, and support files for the entire data set are available separately for downloading:
  • Catalog, index, and support files (374 KB ZIP file)
• MD5 checksums for the above files

The Deep Impact Documentation volume is available as a separate download file:

• Deep Impact Documentation volume (80 MB zip file)

In case you're wondering... What to do with an ISO file What to do with a checksum

An overview of the volume contents is provided in the aareadme.txt file.

Catalog Files

Catalog files contain the overview information and parameters used in loading the PDS central catalog, specifically, or for developing other interfaces to the data outside of PDS. The information they contain, particularly in their descriptive text fields, should be clear, complete, and understandable to a research user who is not necessarily a mission or instrument specialist.

These files are located in the catalog/ subdirectory. The directory contents are described by the catinfo.txt file.

• Deep Impact mission file
• Fly-by Spacecraft instrument host file
• MRI Visible CCD instrument file
• Data Set file
• Target catalog files, containing very brief definitions of the various TARGET_NAME values found in the PDS labels for the data:
  • Calibration target file; the name of a calibration target is provided by TARGET_DESC in the PDS labels.
  • 9P/Tempel 1 target file
• References file
• Personnel file

Documentation Files

The documentation for the Deep Impact mission has been collected into a separate volume. The root of this volume is here. The contents are described in the aareadme file in the root of the documentation volume.

Data Files

The data are grouped by mid-observation date with subdirectories named by sequential day number under the data/2005/ subdirectory.

Index Files

The index/ directory contains the required PDS index into the data files in the data directory, as well as the checksum file.

• indxinfo.txt describes the directory contents.
• index.tab is a CSV table meeting the PDS indexing requirements. (PDS label)
• checksum.tab is flat table of MD5 checksums for each file in the official archive volume except for itself and its PDS label.
