pfsspy.coords Module

Helper functions for coordinate transformations used in the PFSS domain.

The PFSS solution is calculated on a “strumfric” grid defined by

• \(\rho = \log (r)\)

• \(s = \cos (\theta )\)

• \(\phi\)

where \(r, \theta, \phi\) are spherical cooridnates that have ranges

• \(1 < r < r_{ss}\)

• \(0 < \theta < \pi\)

• \(0 < \phi < 2\pi\)

The transformation between cartesian coordinates used by the tracer and the above coordinates is given by

• \(x = r\sin (\theta) \cos (\phi)\)

• \(y = r\sin (\theta) \sin (\phi)\)

• \(z = r \cos (\theta)\)

Functions
