MSL ChemCam EDR CALIB Directory

The CALIB directory will include ChemCam calibration data from various 
environments.

The directroy structure is

    |     |-YYYY_MM_DD_hhmmss.csv, .lbl
    |          Raw spectra in dn with comments that describe the setup and
    |          collection environment.  Values are Digital Number (DN).

ChemCam calibrations carried out in the cleanroom which are being provided
to the PDS consist of Test #6 in Table 7 of Wiens et al. 2012, Space Science
Reviews, and Table 1 of Wiens et al., 2013, Spectrochim. Acta B. These are
essentially equivalent tables. For this test, all standards were observed in
a sample chamber containing 7 Torr (930 Pa) +/-15% of CO2 at room temperature.
The distance from the instrument to the standards was 3 m in all cases. The
laser was configured to provide maximum power but due to the fact that it was
at room temperature, well above its optimum design temperature of -10 C, the
energy per pulse was approximately 10 mJ. The instrument was not refocused
between standards. A titanium plate was installed with each group of standards
in the sample chamber for comparison purposes. One or more of the
demultiplexer dichroic mirrors was/were changed after both the Cleanroom and
TVAC tests. Nominal corrections were made to the processed data by applying
different instrument optical response functions. Further details are provided
in Wiens et al. 2013.
