Deep Impact Flyby Spacecraft
HRII/HRIV/MRI Temperature Measurements

Status: In Lien Resolution

This data set contains resampled (raw, averaged) temperature measurements from 27 sensors located in the HRII, HRIV, and MRI instruments, the HRI and MRI telescopes, the instrument platform, and the solar wings of the Deep Impact flyby spacecraft. The data begin three days after launch and end five days after the encounter with comet 9P/Tempel 1.

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.

Note that the data set catalog file is preliminary and subject to frequent editing until a peer review has been scheduled for these data.

• Deep Impact mission file
• Deep Impact flyby spacecraft instrument host file
• HRII instrument file (IR spectrometer)
• HRIV instrument file (High-Res CCD)
• MRI instrument file (Medium-Res CCD)
• Data Set file
  
• 9P/Tempel 1 target file
• References file
• Personnel file

Documentation Files

In addition to the small text files located throughout the volume to describe directory contents, some specific documents are provided to assist with understanding the data and processing involved. These files are located in the document/ subdirectory. The directory contents are described by the docinfo.txt file.

Documents specific to this data set are:

• The mission time (ASC, PDF, XLS, PDS label) provides a list of daily mission and spacecraft ctivities that may have affected the instrument temperatures
• The following plots illustration some of the variations in measurements from selected temperature sensors:
  • Plot of the thermal changes for two temperature sensors on the HRI telescope during flight (PDS label)
  • Plot of the thermal changes for two temperature sensors for the MRI CCD during flight (PDS label)
  • Plot of the differences between the two temperature sensors for the MRI CCD (PDS label)

Data Files

• HRI Sensors Table (PDS label)
  This ASCII table contains resampled (raw, averaged) measurements from 14 different temperature sensors located at various points on the HRI telescope, the HRI IR spectrometer (HRII), the HRI visible CCD (HRIV) as well as one sensor in the panel underneath the instrument platform and four sensors on the two solar wings on the flyby spacecraft.
• MRI Sensors Table (PDS label)
  This ASCII table contains resampled (raw, averaged) measurements from nine different temperature sensors located at various points on the MRI telescope and the MRI visible CCD on the flyby spacecraft.

Index Files

The index/ directory contains the required PDS index into the files in the data/ directory.

• indxinfo.txt describes the directory contents.
• index.tab is a CSV table meeting the PDS indexing requirements. (PDS label)
