Bases: pytmosph3r.observations.emission.Emission

The Phasecurve module relies on the Emission module: we iterate over n_phases observer longitudes and scale the flux using the projection of the surface onto that direction. You can use the same parameters as Emission for this module. IMPORTANT NOTE: top_flux_from_star and mu_from_obs will add a considerable computing time since the emission flux has to be re-computed at EACH phase.

Parameters:

  • n_phases (int) – Number of phases for the phase curve. Defaults to 100.

  • start (float) – Phase at which to start the phasecurve, in SI (radians) or astropy units.

  • end (float) – Phase at which to end the phasecurve, in SI (radians) or astropy units.

  • phases (array) – List of phases (ignores n_phases, start and end). Assumed to be in

  • SI –

  • units. (or astropy) –

  • kwargs (dict) – Parameters passed to the Emission module.

Returns:

A series of n_phases Emission fluxes.

Return type:

(array)

We provide two methods to select the phases, the first one (1) provide an array with the phases wanted. The second one (2) create the phases array from a number of phase and the bounds.

Parameters:

  • n_phases (Optional[int]) –

  • start (None, float, Quantity[pt.angle]) –

  • end (None, float, Quantity[pt.angle]) –

  • phases (Union[None, np.ndarray, Quantity[pt.angle]]) – Typed array (1)

  • () (**kwargs) –

  • () –

  • () –

n_phases: int

Number of phases in the phase curve.

build(model)[source]

No need for an altitude-based grid (as done in transmission), so we just copy the input grid.

compute(model)[source]

Computation of a phase curve, along n_phases observer longitudes. This function is called by compute().
