Mini-TES Instrument and Operations

For operational information on the Mini-TES please see the Mini-TES web page and FAQ as well as the papers referenced at the end of this page. Especially Christensen et. al. 2003 and 2004. A key calibration note is included in Christensen et. al. (2004) Science above is included here:

Two-point radiometric calibration was intended to use two V-groove blackbody targets (2).
The temperature sensors attached to the rover  deck failed at extremely low temperatures
(~–90°C) on the first night after landing. The calibration was modified to use prelaunch
measurements of the instrument response function taken over temperature, with the instrument
radiance determined from observations of the functioning target mounted in the Pancam mast assembly
(PMA). On the basis of comparison with orbiting MGS TES data and modeling of the atmospheric
observations, the response function has not changed from prelaunch values and the calibration
approach is providing the required accuracy. The 1-sigma radiometric precision for two-spectra
summing is +/-1.8 ϫ 10-8 W cm-2 sr-1 cm-1 between 450 and 1300 cm-1, increasing to
~7 ϫ 10-8 W cm-2 sr-1cm-1 at shorter (300 cm-1) and longer (1800 cm-1)
wave numbers. The absolute radiance error is <5 ϫ 10– 8 W cm–2 sr–1 cm–1,
decreasing to ~1 ϫ 10– 8 W cm–2 sr–1 cm–1
