Input(br, nr, rss)¶
Input to PFSS modelling.
The input must be on a regularly spaced grid in \(\phi\) and \(s = \cos (\theta)\). See
pfsspy.gridfor more information on the coordinate system.
br (sunpy.map.GenericMap) – Boundary condition of radial magnetic field at the inner surface. Note that the data must have a cylindrical equal area projection.
nr (int) – Number of cells in the radial direction to calculate the PFSS solution on.
rss (float) – Radius of the source surface, as a fraction of the solar radius.
