Our data came from two tools on the Rover, Laser-induced breakdown spectroscopy (LIBS) and physical samples taken from the ground and put into tubes to be studied.
Of the LIBS data, we have two types.
- LIBS scans of Mars rock
- LIBS scans of Earth rock taken to Mars to be used for calibration (scct)
| Col name: | Data type: | Levels: | What: |
|---|---|---|---|
| Target | Character | Name of location the LIBS was taken | |
| Point | Factor | 1 - 28 | |
| Sol | Numeric | Int > 0 | The Mars day (since start of mission) that the rover took the LIBS point was taken |
| Lat | Numeric | Where the rover was when the LIBS point was taken | |
| Lon | Numeric | Where the rover was when the LIBS point was taken | |

Feature data is the same as PIXL, concentration of elemental compounds, though without a few of the elemental compounds PIXL includes. It also has the addition of standard deviations, Total, etc, which PIXL doesn't have.
Only the "scct" targets. That is, only the earth references. Note that none of these earth references are in the normal LIBS data frame.
