title: Replication Data for: Thermophysical diversity of young lunar crater ejecta revealed with LRO Diviner observations

description: &lt;h2&gt;&lt;b&gt;Contents&lt;/b&gt;&lt;/h2&gt;
For each crater region of interest (ROI), this dataset contains:

&lt;h3&gt;Raw data:&lt;/h3&gt;
&lt;ul&gt;
 &lt;li&gt;Bolometric temperatures and propagated uncertainties binned at 128 pixels per degree (ppd).&lt;/li&gt;
 &lt;ul&gt;
 &lt;li&gt;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 &lt;a href="https://pgda.gsfc.nasa.gov/products/54"&gt;(SLDEM2015)&lt;/a&gt;; see description in &lt;a href="https://doi.org/10.1016/j.icarus.2015.10.034"&gt;Williams et al. (2016)&lt;/a&gt; & &lt;a href="https://doi.org/10.1016/j.icarus.2017.04.007"&gt;Sefton-Nash et al. (2017)&lt;/a&gt;&lt;/li&gt;
 &lt;li&gt;Bolometric temperatures are calculated from the binned radiances in each of the seven Diviner thermal channels (ch. 3-9) using the algorithm of &lt;a href="https://doi.org/10.1126/science.1187726"&gt;Paige et al. (2010)&lt;/a&gt;&lt;/li&gt;
 &lt;li&gt;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)&lt;/li&gt;
 &lt;li&gt;Bolometric temperatures and uncertainties are in units of kelvin&lt;/li&gt;
 &lt;li&gt;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&lt;/li&gt;
 &lt;li&gt;Bolometric temperatures are corrected for solar distance (normalized to 1 AU)&lt;/li&gt;
 &lt;/ul&gt;
&lt;/ul&gt;

&lt;h3&gt;GeoTIFF files:&lt;/h3&gt;
&lt;ul&gt;
 &lt;li&gt;&lt;u&gt;Multi-band files:&lt;/u&gt;&lt;/li&gt;
 &lt;ul&gt;
 &lt;li&gt;RGB composite of model output in byte (0-255 normalized) and float (original model values) format, with separate folders for masked data (&lt;i&gt;H&lt;sub&gt;1param&lt;/sub&gt;&lt;/i&gt; 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.&lt;/li&gt;
 &lt;/ul&gt;
 &lt;li&gt;&lt;u&gt;Single-band files:&lt;/u&gt;&lt;/li&gt;
 &lt;ul&gt;
 &lt;li&gt;Individual files for &lt;i&gt;ΔT&lt;/i&gt;&lt;sub&gt;BOL&lt;/sub&gt;, &lt;i&gt;I&lt;sub&gt;d,273K&lt;/sub&gt;&lt;/i&gt;, and &lt;i&gt;H&lt;/i&gt; for both masked and unmasked two-parameter model output (R, G, and B channels respectively in corresponding RGB composite file)&lt;/li&gt;
 &lt;li&gt;Best fit &lt;i&gt;H&lt;/i&gt;-parameter values for the one-parameter model&lt;/li&gt;
 &lt;li&gt;Root-mean-square error (RMSE) between model and data (normalized by degrees of freedom) for both the one-parameter and two-parameter models&lt;/li&gt;
 &lt;li&gt;Reduced chi-squared values between model and data (weighted by bolometric temperature uncertainties) for both the one-parameter and two-parameter models&lt;/li&gt;
 &lt;/ul&gt;
&lt;/ul&gt;


&lt;h3&gt;Shapefiles:&lt;/h3&gt;
&lt;ul&gt;
 &lt;li&gt;Shapefiles of the mask boundary between the one-parameter and two-parameter model results (&lt;i&gt;H&lt;sub&gt;1param&lt;/sub&gt;&lt;/i&gt; values given in file name)&lt;/li&gt;
&lt;/ul&gt;
