sunkit_magex.pfss.analytic Module

Analytic inputs and solutions to the PFSS equations.

This sub-module contains functions to generate solutions to the PFSS equations in the case where the input field is a single spherical harmonic, specified with the spherical harmonic numbers l, m.

All angular quantities must be passed as astropy quantities. All radial quantities are passed normalised to the source surface radius, and therefore can be passed as normal scalar values.

Angular definitions

• theta is the polar angle, in the range \(0, \pi\) (ie. the co-latitude).

• phi is the azimuthal angle, in the range \(0, 2\pi\).

Using this module requires sympy to be installed.

Functions

Bphi(l, m, zss)	Analytic phi component of magnetic field on the source surface.
Br(l, m, zss)	Analytic radial component of magnetic field on the source surface.
Btheta(l, m, zss)	Analytic theta component of magnetic field on the source surface.
