jeanspy.model_jax.AxisymmetricDSphModel.intrinsic_moments

Class and construction: AxisymmetricDSphModel.

AxisymmetricDSphModel.intrinsic_moments(R_pc, z_pc, *, params)[source]#

Evaluate the intrinsic Jeans second moments.

Notes

Inputs and units. R_pc >= 0 and signed z_pc in pc, broadcastable; params supplies the physical dictionary.

Returns and shape. Tuple (vR2,vz2,vphi2), each in (km/s)^2 with the broadcast coordinate shape. vphi2 is the total azimuthal second moment; no rotation/dispersion split is assigned.
