Supporting Data for: Chromium on Mercury: New results from the MESSENGER X-Ray Spectrometer and implications for the innermost planet’s geochemical evolution

<p>Research data supporting Chromium on Mercury project and the paper "Chromium on Mercury: New results from the MESSENGER X-Ray Spectrometer and implications for the innermost planet’s Geochemical evolution," in the Journal of Geophysical Research.</p>

<p>The primary underlying data is archived by <a href="https://pds.nasa.gov">NASA Planetary Data System (PDS)</a>. This subset includes additional data (one spreadsheet and eighteen images) not archived by NASA. </p>

<p>The spreadsheet contains the fitting results for 133 MESSENGER XRS flare spectra reported in Nittler et al. (Chromium on Mercury: New results from the MESSENGER X-Ray Spectrometer and implications for the innermost planet’s geochemical evolution). </p>

<p>As discussed in the paper, the Cr/Si and Fe/Si ratios are corrected for the phase angle effect. Both corrected, and uncorrected data are provided for Cr/Si. Error bars are one-sigma. Errors are statistical, and systematic error bars may be larger. MXRS data are available from the NASA PDS</a>.</p>

<p>Dataset contains 18 images, 1 spreadsheet - 'crflaredata.csv,' and 1 README documentation file providing the methodology and variable information. Approximately 3 megabytes.</p>
