jeanspy.model_jax.PlummerModel.density_3d

Class and construction: PlummerModel.

PlummerModel.density_3d(r_pc, *, re_pc)[source]#

Return unit-normalized Plummer density in pc^-3 on the JAX backend.

r_pc is an intrinsic scalar/array radius in pc and re_pc is the positive projected half-light scale in pc. Output follows broadcasting; the expression is differentiable within the valid domain. This elementary helper does not validate physical parameter values.

Parameters:
Return type:

jax.Array
