density_3d

jeanspy.model.PlummerModel.density_3d

Class and construction: PlummerModel.

PlummerModel.density_3d(r_pc)

Evaluate the unit-normalized intrinsic tracer density.

Parameters:

r_pc (float or numpy.ndarray) – Nonnegative intrinsic radius in pc; NumPy array inputs keep their shape.

Returns:

float or numpy.ndarray – Density in pc^-3 with the input radius shape.

Notes

The Plummer central density is finite. Stored tracer scales must be positive. This elementary NumPy formula does not uniformly validate input domains; no JAX physical-parameter differentiation is supported.
