Mercury's crustal thickness correlates with lateral variations in mantle melt production: Dataset for maps of surface density, degree of partial melting, and crustal thickness

1) DensityGrid.dat = map of density of pore-free surface rocks (Figure 1a)

- Units = g/cm3

- 720 x 1440 pixels corresponding to 0.25-degree pixels in an equirectangular cylindrical projection with the equator as central parallel.

- The first row represents 90 to 89.75 degrees of latitude north; the last row represents 89.75 to 90 degrees of latitude south.

- The first column represents 0 to 0.25 degree of longitude; the last column represents 359.75 to 360 degrees of longitude.

2) MeltGrid.dat = map of degree of partial melting (Figure S1a)

- Units: mass fraction

- 720 x 1440 pixels as described above

3) CrustalThickness_ModelU0.dat = map of crustal thickness if laterally uniform density, Model U0 (Figure 2a)

    CrustalThickness_ModelVn.dat = map of crustal thickness if laterally variable density, Model Vn (Figure 2c, Figures S6 to S10)

- Units = km

- generated with MakeGridDH of SHTOOLS (https://shtools.github.io/SHTOOLS/)

- 720 x 1440 coordinate points corresponding to 0.25-degree spacing in an equirectangular cylindrical projection with the equator as central parallel.

- The first row corresponds to 90 degrees of latitude north; the last row corresponds to 89.75 degrees of latitude south.

- The first column corresponds to 0 degree of longitude; the last column corresponds to 359.75 degrees of longitude.
