ld_to_kipping#
- luas.exoplanet.transit_fns.ld_to_kipping(u1: Array, u2: Array) Tuple[Array, Array][source]#
Converts quadratic limb darkening parameters to the Kipping (2013) parameterisation from the standard quadratic limb darkening coefficients:
\[I(r) = 1 − u_1(1 − \mu) − u_2(1 − \mu)^2\]Values are converted using:
\[q_1 = (u_1 + u_2)^2\]\[q_2 = \frac{u_1}{2(u_1 + u_2)}\]- Parameters:
u1 (JAXArray) – First quadratic limb darkening coefficient(s).
u2 (JAXArray) – Second quadratic limb darkening coefficient(s).
- Returns:
The first and second quadratic limb darkening coefficient(s) in the Kipping (2013) parameterisation.
- Return type:
(JAXArray, JAXArray)
