sample_R

jeanspy.model_jax.PlummerModel.sample_R

Class and construction: PlummerModel.

PlummerModel.sample_R(key, n, *, re_pc)

Sample projected radii using the analytic inverse CDF.

CDF(R) = R^2 / (R^2 + re^2) -> R = re * sqrt(u/(1-u)).

Notes

Inputs and units. key is a JAX random key; n is a static nonnegative count; re_pc is positive scale in pc.

Returns and shape. Array (n,) of radii in pc. Split keys explicitly before repeated independent draws.

Parameters:

• key (jax.Array)

• n (int)

• re_pc (Any)

Return type:

jax.Array
