Constructs a yellow sphere representing the solar surface and reads in four different data files containing the open field lines, the heliospheric current sheet, the belt, and the eqss field lines that can be displayed separately or together. The data files that were extracted from a MAS simulation.
The page {template} contains the template for importing each of these data, using the Select modules to pick the x, y, and z components of the field and feeding them into Make3DField to construct a 3-D field which in turn can be displayed.
