FIDO August 2002 Field Test   Home

Overview

This web site is the Analyst's Notebook (AN) for the August 2002 field test of FIDO, a Mars rover prototype. The intent of AN is to document the field test by providing the following information:

  • test plans, actions, and results
  • raw scientific and engineering data
  • scientific data processed as standard and special products

Available data

The AN contains all scientific and engineering data produced as experiment data records (EDRs) during the field test. The EDRs are processed into standard and special products in browse and full-resolution versions. The following table summarizes data typically returned during a field test. (Items in italics are not available currently.)

Instrument Standard Products Special Products

Images

Browse versions of standard and special products are available from this site. Note that the thumbnail and full-resolution browse images are in JPEG format for portability. The JPEG format uses a lossy compression scheme, thus browse versions of image data are degraded from the original and should not be used for scientific analysis. Full-quality versions of standard and special products are available as TIFF images via ftp (see 'Accessing the data' below).

ASCII tables

IPS raw and processed data are available as ASCII tables. The processed data table has 10 columns as follows:

Col Contents
1 Wavelengths; NOT identical to IPS output wavelengths... these are the
corrected values
2 Dark current; This value is not used in the current processing scheme
(it's just filler right now)
3 Reference; The raw reference spectrum
4 Data; The raw data spectrum
5 Smoothed reference; Raw reference spectrum run through a 31-point smooth
6 Smoothed data; Raw data spectrum run through a 31-point smooth
7 Corrected reference; The smoothed reference minus a simulated dark
current
8 Corrected data; The smoothed data minus a simulated dark current
9 Radiance coefficient; (Corrected data) / (Corrected reference)
10 Error; 1-sigma error as determined from analyzing the bottom of the
1.85 um H2O band

Further information

Information about the science instruments is available from the JPL FIDO Rover web site.

Available documentation
An all-inclusive document describing the field test is not available from with the AN. However, comments from the science team are integrated into the notebook and are displayed as appropriate. Further information is available from the JPL FIDO Rover web site.

Accessing the data

The entire contents of the Analyst's Noteobook, including data, documentation, and support files, are available via a combination of the web and ftp (file transfer protocol). The web interface should be used for accessing browse products and documentation, and for understanding synergies within the data. Ftp access should be used to access full-quality data products and the original EDRs.

AN web interface

In the current version of the AN, data returned from the rover are grouped into events. An event is defined as a sequence of one or more consecutive EDRs from a given instrument, with no intervening EDRs from another instrument. Events are listed in summary tables ordered by sol, by instrument, and by target (when targets have been identified). Abbreviations are used in the summary table to save space. Below is a legend for the summary table column headings.

Column Content
Sol Event sol
S Rover site
P Rover position
I Instrument
Time Event start time; a time source may be appended as a superscript (1=WITS, 2=Approximation, 3=COT notes)
Event Event summary

Instruments are identified by symbols within the summary tables to facilitate quick visual scans through the data. Clicking on an instrument symbol will link to a summary table of events for that symbol. The symbol key is as follows.

Rover commands Microscopic Imager Front Hazcam 
IR Point Spectrometer Pancam Rear Hazcam
Raman Spectrometer Moessbauer Spectrometer Bellycam
Mini-Corer Navcam

Event pages contain data from all EDRs of an event, including associated browse products in thumbnail version. From the event page the user may may access full-resolution browse products and complete engineering telemetry. Note that browse products are degraded in quality and should not be used for scientific analysis.

AN ftp interface

Full-quality data products and EDRs are available via ftp to the same address as the AN web version. The directory structure of the AN is shown below.

| |- fronthaz Data products for front hazcam
| |- ips Data products for IPS
