Three-Dimensional Seismic P-Wave Velocity Model of the Lunar Mantle

The 3D seismic structure of the Moon is given in spherical_ascii.dat (spherical coordinates), with P-wave velocities at each point stored in vp_spherical_ascii.dat. In these files, radial distances are given in kilometers (km), angular values are in radians, and P-wave velocities are in meters per second (m/s). The velocities in the crust and core are assigned manually and not computed by the model. A one-dimensional averaged profile of the P-wave velocity is provided in Vp_prof_1.dat. The radius values are in meters (m), and the P-wave velocities are in meters per second (m/s).
