exotic_ld.ld_laws.kipping_ld_law(mu, q1, q2)

Kipping limb-darkening law.

\[\frac{I(\mu)}{I(\mu = 1)} = 1 - u_1 (1 - \mu) - u_2 (1 - \mu)^2,\]

where,

\[ \begin{align}\begin{aligned}u_1 &= 2 \sqrt{q_1} q_2,\\u_2 &= \sqrt{q_1} (1 - 2 q_2),\end{aligned}\end{align} \]

and \(\mu = \sqrt{1 - r^2}\), and \(q_1\), \(q_2\) are the limb-darkening coefficients.
