jaxon.reflected.reflected_phase_curve_inhomogeneous(phases, omega_0, omega_prime, x1, x2, A_g, a_rp)[source]

Reflected light phase curve for an inhomogeneous sphere by Heng, Morris & Kitzmann (2021), with inspiration from Hu et al. (2015).

Parameters
  • phases (~np.ndarray) – Orbital phases of each observation defined on (0, 1)

  • omega_0 (tensor-like) – Single-scattering albedo of the less reflective region. Defined on (0, 1).

  • omega_prime (tensor-like) – Additional single-scattering albedo of the more reflective region, such that the single-scattering albedo of the reflective region is omega_0 + omega_prime. Defined on (0, 1-omega_0).

  • x1 (tensor-like) – Start longitude of the darker region [radians] on (-pi/2, pi/2)

  • x2 (tensor-like) – Stop longitude of the darker region [radians] on (-pi/2, pi/2)

  • a_rp (float, tensor-like) – Semimajor axis scaled by the planetary radius

Returns

  • flux_ratio_ppm (tensor-like) – Flux ratio between the reflected planetary flux and the stellar flux in units of ppm.

  • g (tensor-like) – Scattering asymmetry factor on (-1, 1)

  • q (tensor-like) – Integral phase function
