chi_p_prior_from_isotropic_spins(chi_p, q, a_max=1.0)

Calculate the conditional prior density for effective precession \(p(\chi_\mathrm{p}\mid q)\) corresponding to uniform and isotropic component spin priors.

Parameters:

chi_pfloat, array-like

Effective precession value(s) at which to compute the prior density.

qfloat, array-like

Mass ratio value(s) to condition on. Expected convention \(q<1\).

a_maxfloat, default=1.0

Maximum allowed dimensionless component spin magnitude.

Returns:

array-like

Prior density at given effective spin value(s).
