Synthetic data for the solution of geophysical inverse problems

<p>The synthetic LAB used to define an inverse problem is&nbsp;discretized in different number of parameters. Each &nbsp;&quot;LAB&quot; file is one specific&nbsp;discretization and&nbsp;contains the coordinatates X and Y and the value of the LAB&nbsp;at each position</p> <p>The reference velocity fields obtained from solving the Stokes equation with the synthetic LABs are&nbsp;found in &quot;velo&quot; files. They contain, X, Y, and Z and the field Vx, Vy and Vz.</p> <p>Another synthetic data set represents the&nbsp;african lithosphere. The first two columns of its&nbsp;LAB file contain the longitude and latitude of each point and the third column is the value of the LAB. The reference velocity field obtained from solving Stokes is &nbsp;found&nbsp;in the corresponding &quot;velo&quot; file.</p>
