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.
