CONAN._classes.load_rvs.planet_parameters(T_0=0, Period=0, Eccentricity=None, omega=None, sesinw=None, secosw=None, K=0, verbose=True)#

Define parameters and priors of RV model. By default, the parameters are fixed to the given values. The parameters can be defined in following ways:

  • fixed value as float or int, e.g Period = 3.4

  • gaussian prior given as tuple of len 2, e.g. T_0 = (5678, 0.1)

  • uniform prior interval given as tuple of length 3, e.g. K = (0,10,100) with 10 being the initial value.

Parameters:

  • T_0 (float, tuple;) – Mid-transit (inferior conjunction) time in days. Default is 0.

  • Period (float, tuple;) – Orbital period of the planet in days. Default is 0.

  • Eccentricity (float, tuple;) – Eccentricity of the orbit. Default is None to use sesinw and secosw parameterization.

  • omega (float, tuple;) – Argument of periastron in degrees. Default is None to use sesinw and secosw parameterization.

  • sesinw (float, tuple,) – √esinw, √ecosw. alternate parameterization of eccentricty and omega. Default is None which fixes both values to 0, which implies Eccentricity=0, omega=90

  • secosw (float, tuple,) – √esinw, √ecosw. alternate parameterization of eccentricty and omega. Default is None which fixes both values to 0, which implies Eccentricity=0, omega=90

  • K (float, tuple;) – Radial velocity semi-amplitude in same unit as the data. Default is 0.

  • verbose (bool;) – print output. Default is True.
