Orbit (galpy.orbit)

See Orbit initialization for a detailed explanation on how to set up Orbit instances.


In addition to these methods, any calculable attribute listed below can be plotted versus other attributes using plotATTR, where ATTR is an attribute like R, ll, etc. In this case, the y axis will have ATTR and the overridable x axis default is time. For example, o.plotR() will plot the orbit’s R vs time.


  • Orbit.name Name(s) of objects initialized using ``Orbit.from_name``[source]
  • Orbit.shape Tuple of Orbit dimensions
  • Orbit.size Total number of elements in the Orbit instance
