Direct discontinuous Galerkin method for potential magnetic field solutions

The data set includes the data of grid system, the data of the radial magnetic field obtained from the spherical harmonic expansion method and the DDG-PFSS solver, the data of topologies of the coronal magnetic fields on a meridional plane, the data of coronal holes, the data of pB at 2.5 solar radius, the data of the magnetic flux tube expansion factor and the minimum angular separation between an open magnetic fifield footpoint and its nearest coronal hole boundary, and the data at 1 AU of radial velocity.
