title: Data for "Assessment of InSight Landing Site Predictions"

description: This file describes data related to Golombek et al. 2020 submission "Assessment of InSight Landing Site Predictions" to the Journal of Geophysical Research: Planets. Questions regarding these data or the paper should be directed to Matthew.P.Golombek@jpl.nasa.gov or Nathan.R.Williams@jpl.nasa.gov.
 
This .zip archive contains data used in the analyses contained within the paper and its figures. All coordinates are reported in an equirectangular projection with a planetary radius 3396190 corresponding to the IAU/IAG Mars 2000 positive east planetocentric coordinate system, and all measurements are reported in meters. If desired, to convert coordinates (reported as meters easting and northing) to degrees, multiply by [360/(2*pi*3396190)].
 
Listing of files:
 
- HiRISE_150m_CFA_Mosaic.tif: this image corresponds to the data shown in Figure 5, and represents the cumulative fractional area of rocks derived from the fit of rocks between 1.5 m and 2.25 m diameter to exponential models within 150x150m bins as detected in HiRISE images across the InSight landing ellipse. This data was also used to create Figures 7 and 8. Values are stored as 8-bit unsigned integers and correspond to the rounded % CFA. This file is a geotiff with spatial reference information contained within the file's header.
 
- HiRISE_Rock_Counts.csv: this comma-separated value file includes columns for the longitude, latitude, and diameter (all in meters) of all rocks detected in HiRISE images across the InSight landing ellipse, as shown in Figures 6 and 9.
 
- Ground_Rock_Counts.xls: this Microsoft Excel file contains a series of sheets, one for each plot of rock CFA versus diameter in Figure 10, of rock counts performed using ground-based images from InSight, Phoenix, and Spirit. Columns for each sheet include the rock diameter (m), cumulative number of rocks per m^2 larger than the diameter given, binned/incremental number per meter squared, and CFA measured as a decimal (table value of 1 = 100% CFA) for the given diameter.
 
- Secondary_Craters_CoordinatesDiams.csv: this comma-separated value file includes columns for the longitude, latitude, and diameter (all in meters) of all secondary craters identified in HiRISE image ESP_036761_1845_RED within and bordering a 500x500m box surrounding InSight's landing location, as shown in Figure 12a.
 
- Regolith_minthickness_delaunay.tif & *.tfw: Delaunay triangulation result showing the interpolation of the depth of excavation for all 30-60 m diameter non-rocky ejecta craters in the InSight landing ellipse, corresponding to Figure 15. Values are stored as 32-bit floating point numbers representing meters depth. The *.tif contains the image data, and the *.tfw is an associated world file containing spatial referencing information.
 
- Regolith_maxthickness_delaunay.tif & *.tfw: Delaunay triangulation result showing the interpolation of the depth of excavation for all 30-60 m rocky ejecta craters in the InSight landing ellipse, corresponding to Figure 16. Values are stored as 32-bit floating point numbers representing meters depth. The *.tif contains the image data, and the *.tfw is an associated world file containing spatial referencing information.
 
- Regolith_50pc_thickness_delaunay.tif & *.tfw: Delaunay triangulation result showing the average of min and max thicknesses of the regolith from the depth of excavation for all 30-60 m diameter non-rocky and rocky ejecta craters in the InSight landing ellipse, corresponding to Figure 17. Values are stored as 32-bit floating point numbers representing meters depth. The *.tif contain the image data, and the *.tfw is an associated world file containing spatial referencing information.
