class CONAN.models.Planet_LC_Model(rho_star=None, dur=None, T0=None, RpRs=None, b=None, per=None, sesinw=[0], secosw=[0], ddf=0, q1=0, q2=0, occ=0, Fn=None, delta=None, A_ev=0, A_db=0, f1_ev=0, cst_pars={}, npl=1)#

computes the transit model for a given set of parameters along with the baseline

Parameters:

  • rho_star (float) – Stellar density [g/cm^3]

  • T0 (float) – Mid-transit time [days]

  • RpRs (float) – Planet-to-star radius ratio

  • b (float) – Impact parameter

  • per (float) – Orbital period [days]

  • sesinw (float) – sqrt(ecc)*sin(omega)

  • secosw (float) – sqrt(ecc)*cos(omega)

  • ddf (float) – if ddf is not 0, then depth variation is being used and this value is added to the base rprs, grprs.

  • q1 (float) – LD coefficient 1

  • q2 (float) – LD coefficient 2

  • occ (float) – Occultation depth

  • Fp (float) – nightside flux ratio

  • delta (float) – hotspot shift of the atmospheric variation in degrees

  • A_ev (float) – semi-Amplitude of the ellipsoidal variation

  • f1_ev (float;) – fractional constant of the EV model

  • A_db (float) – semi-Amplitude of the Doppler boosting

  • cst_pars (dict) – additional parameters for the custom light curve function. Default: {}

  • npl (int) – number of planets

Returns:

marr – The lightcurve model for the given parameters

Return type:

array-like
