class jeanspy.model_jax.AxisymmetricPlummerModel

Bases: jeanspy.axisymmetric.AxisymmetricStellarModel

Functional JAX Plummer tracer with explicit re_pc and q/q_projected.

Distances are pc; density is normalized to unity. q_projected requires an admissible oblate inclination in radians. Dynamic invalid values yield NaN; schema errors raise ValueError. Supports JIT and physical-parameter gradients.

density_3d(R_pc, z_pc, *, params)

Return unit-normalized pc^-3 density at broadcast cylindrical coordinates.

radial_derivative(R_pc, z_pc, *, params)

Return dnu/dR in pc^-4; invalid dynamic coordinates yield NaN.

surface_density(x_pc, y_pc, *, params)

Return projected normalized pc^-2 density; x is the line of nodes.
