JF12Field
: public MagneticField¶ JF12Field galactic magnetic field model.
Implements the JF2012 magnetic field model, consisting of a large-scale regular and random (striated) field and a small-scale random (turbulent) field. See: Jansson 2012a, ApJ. 757, A New Model of the Galactic Magnetic Field Jansson 2012b, arXiv:1210.7820, The Galactic Magnetic Field
All three components may individually turned on and off. Currently only best fit values of the field paramaters are implemented and cannot be changed.
The field is defined in the usual galactocentric coordinate system with the Galactic center at the origin, the x-axis pointing in the direction of the Sun, and the z-axis pointing towards Galactic north.
