class CMZField : public MagneticField 

Magnetic Field Model in the Galactic Center from M. Guenduez et al.

Poloidal Model (Model C) is taken from Katia Ferriere and Philippe Terral 2014 “Analytical models of X-shape magnetic fields in galactic halos” [arXiv:1312.1974] Azimuthal Model is taken from M.Guenduez, J.B. Tjus, K.Ferriere, R.-J. Dettmar (2019) [arXiv:1906.05211]

Vector3d BPol(const Vector3d &position, const Vector3d &mid, double B1, double a, double L) const

Magnetic field in the poloidal model. Used for inter-cloud (IC), non-thermal-filaments (NTF) and for the radio arc.

Parameters:

position – position in galactic coordinates with Earth at (-8.5kpc, 0,0)
mid – midpoint of the object
B1 – normalized magnetic field strength
a – fitting parameter for the radial scale height
L – fitting parameter for the z scale height

Returns:

magnetic field vector

Vector3d BAz(const Vector3d &position, const Vector3d &mid, double B1, double eta, double R) const

Magnetic field in the azimuthal model. Used for molecular clouds (MC)

Parameters:

position – position in galactic coordinates with Earth at (-8.5kpc, 0,0)
mid – midpoint of the object
B1 – normalized magnetic field strength
eta – ratio between radial and azimuthal component
R – Radius of the cloud

Returns:

magnetic field vector
