# Input¶

class pfsspy.Input(br, nr, rss)

Bases: object

Input to PFSS modelling.

Warning

The input must be on a regularly spaced grid in $$\phi$$ and $$s = \cos (\theta)$$. See pfsspy.grid for more information on the coordinate system.

Parameters
• 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.
