<h2><b>Contents</b></h2> For each crater region of interest (ROI), this dataset contains: <h3>Raw data:</h3> <ul> <li>Bolometric temperatures and propagated uncertainties binned at 128 pixels per degree (ppd).</li> <ul> <li>For each original point-like observation in each detector, a Monte Carlo sampling of 100 points is projected through the calculated Diviner effective field-of-view (EFOV) onto an icosahedral mesh interpolated to the 256ppd LOLA/Kaguya TC merged DEM <a href="https://pgda.gsfc.nasa.gov/products/54">(SLDEM2015)</a>; see description in <a href="https://doi.org/10.1016/j.icarus.2015.10.034">Williams et al. (2016)</a> & <a href="https://doi.org/10.1016/j.icarus.2017.04.007">Sefton-Nash et al. (2017)</a></li> <li>Bolometric temperatures are calculated from the binned radiances in each of the seven Diviner thermal channels (ch. 3-9) using the algorithm of <a href="https://doi.org/10.1126/science.1187726">Paige et al. (2010)</a></li> <li>Data are in tabular text format separated by spaces and ordered by longitude, latitude, and (average) local time of each binned observation (0-24 hr, 0 = local midnight)</li> <li>Bolometric temperatures and uncertainties are in units of kelvin</li> <li>Additional data for each 128ppd bin include: solar distance at time of measurement (AU), average emission angle of the binned observation (degrees), and number of EFOV-projected data points within the bin</li> <li>Bolometric temperatures are corrected for solar distance (normalized to 1 AU)</li> </ul> </ul> <h3>GeoTIFF files:</h3> <ul> <li><u>Multi-band files:</u></li> <ul> <li>RGB composite of model output in byte (0-255 normalized) and float (original model values) format, with separate folders for masked data (<i>H<sub>1param</sub></i> given in file name) and original two-parameter model output. Byte format files have a 2-98% stretch applied to each channel before mapping to final values.</li> </ul> <li><u>Single-band files:</u></li> <ul> <li>Individual files for <i>ΔT</i><sub>BOL</sub>, <i>I<sub>d,273K</sub></i>, and <i>H</i> for both masked and unmasked two-parameter model output (R, G, and B channels respectively in corresponding RGB composite file)</li> <li>Best fit <i>H</i>-parameter values for the one-parameter model</li> <li>Root-mean-square error (RMSE) between model and data (normalized by degrees of freedom) for both the one-parameter and two-parameter models</li> <li>Reduced chi-squared values between model and data (weighted by bolometric temperature uncertainties) for both the one-parameter and two-parameter models</li> </ul> </ul> <h3>Shapefiles:</h3> <ul> <li>Shapefiles of the mask boundary between the one-parameter and two-parameter model results (<i>H<sub>1param</sub></i> values given in file name)</li> </ul>
