Following the release to the Planetary Data System of mirror-dust-corrected Mini-TES spectra from the Spirit rover, these data are now available through the PDS Analyst’s Notebook site:

As described in the “What’s new” section, this data set was prepared by Steve Ruff and funded by the NASA PDART program. It is archived by the PDS Geosciences Node. The new data set adds mirror-dust-corrected emissivity, emissivity standard deviation, and target temperature data products to existing Spirit rover Mini-TES data in the Notebook. Graphs of the emissivity and emissivity standard deviation products are included.
