- gala.dynamics.nonlinear.surface_of_section(orbit, constant_idx, constant_val=0.0)[source]#
Generate and return a surface of section from the given orbit.
The input orbit to generate a surface of section for.
Integer that represents the coordinate to record crossings in. For example, for a 2D Hamiltonian where you want to make a SoS in \(y-p_y\), you would specify
constant_idx=0(crossing the \(x\) axis), and this will only record crossings for which \(p_x>0\).
at the plane, instead of just at the orbital position closest to the plane.
