Description

e#_output_##.dat:

Data and modeled results containing the topographic profiles and axisymmetric flexure modeling corresponding to figures 3a, 4a, and 5a. Two files for each profile exist corresponding to E = 5, 65 GPa.
Columns are as follows:
-    profile #
-    distance from beginning of profile (m)
-    detrended stereo elevation (m)
-    best fit he (km)
-    modeled deflection outboard of load (m)
-    radial flexural stress (Pa)

-------------------------------------------------------------

fig3b_profile5.dat:

Data corresponding to figure 3b, he vs RMS misfit for different combinations of r1 and r2 for profile 5. Columns are as follows:
-    he (km)
-    r1 (km)
-    r2 (km)
-    RMS misfit (m)

-------------------------------------------------------------

fig_4b_all.dat:

Data corresponding to figure 4b, he vs RMS misfit for all profiles. Columns are as follows:
-    profile #
-    he (km)
-    RMS misfit (m)
