Build_theta

class sf3dmodels.grid.Build_theta(GRID)[source] [edit on github]

Bases: sf3dmodels.grid.GridSet

Computes the polar angle \(\theta\) on each cartesian grid point.
\[\theta = \cos^{-1}\left(\frac{z}{r}\right) \]
Parameters:
GRID : Struct

Grid structure to compute.
Attributes:
theta : numpy.ndarray, shape (GRID.NPoints,)

Array of angles in radians, in the range [0, pi/2] if \(z>=0\), and [pi/2, 0] if \(z<0\); where \(\theta=\) pi/2 on the plane \(z=0\).
