Stardust NAVCAM Early Cruise Image Data

Status: Safed

This volume contains navigational camera (NAVCAM) images from the early cruise phase of the Stardust mission. It covers the period 07 February 1999 through 29 October 2001. The Stardust project notes that:

    This volume contains the results of the early cruise images of the
    Stardust Navigation Camera.  These images are of no clear scientific or
    engineering use. They were acquired to ascertain the state of the camera
    during a time of successive contaminations and decontamination actions,
    as described in detail below. None are considered useful for calibration
    of future scientific images, given the nearly continuous changes in the
    state of the camera during this period.

Consequently, the primary goal of this archiving effort is to preserve the bytes and as much documentation as is available, should the data become significant to some unanticipated future effort. The data are available for downloading as is.

• ZIP file of entire volume (142 Mb), for downloading

An overview of the volume contents is provided in the aareadme.htm file. A flat text version of this file is contained in aareadme.txt, with the corresponding PDS label in aareadme.lbl.

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.

• Stardust mission file
• Spacecraft instrument host file
• NAVCAM instrument file
• Data Set file
• "CALIMG" target 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.

• lblinfo.txt and onlabels.txt provide basic information on PDS label structure, with a data label file example.

In the calrpt/ subdirectory:

• calibrpt.pdf contains the calibration report and all supporting tables and graphs. The tables have been extracted into separate text or CSV files in the document/calrpt/ subdirectory.
• calrpt.lbl contains the PDS label for all the .pdf, .txt and .csv files in this subdirectory.

In the scdesc/ subdirectory:

• aerogel.pdf contains the descriptive Aerogel brochure produced by JPL.
• scdesc.htm is the first page of an HTML tree providing spacecraft description, including diagrams.
• scdesc.lbl contains the PDS label for all document files in this subdirectory.

Note that the images referenced in the HTML document actually reside in the separate document/images/ subdirectory. No label was provided for these image files.

Data Files

All image files are located in the data/ subdirectory. Labels are attached to the data.

These images may be viewed using the NASAView package available from PDS Central Node. A version of this software is provided on the volume in the software/ directory, but for the latest version users should download the package from the PDS Central Node web site.

An errata.txt file is provided in the root directory of the volume. Note that some of the errors listed make the labels attached to these image files syntactically invalid. Consequently, there is no guarantee that even PDS software will read them correctly.

Index Files

This directory contains an index into the data files included on this volume (in the data/ directory).

• indxinfo.txt describes the directory contents.
• index.lbl describes the contents of the various other index.* files:
  • index.tab: the fixed-width, delimited version of the index table
  • index.hdr: a CSV-format header file for the index table
  • index.csv: combined header and data in CSV format

Software Files

The software/ directory contains a versions of the NASAview tool for three operating systems. The contents are describes in the softinfo.txt file.
