Ephemeris

class lcviz.plugins.ephemeris.ephemeris.Ephemeris(*args, **kwargs)

Bases: PluginTemplateMixin, DatasetSelectMixin

See the Ephemeris Plugin Documentation for more details.

Only the following attributes and methods are available through the public plugin API:

• show()

• open_in_tray()

• close_in_tray()

• component (EditableSelectPluginComponent): Label of the component corresponding to the active ephemeris.

• t0 : float Zeropoint of the ephemeris.

• period : float Period of the ephemeris, defined at t0.

• dpdt : float First derivative of the period of the ephemeris.

• wrap_at : float Phase at which to wrap (phased data will encompass the range 1-wrap_at to wrap_at).

• ephemeris()

• ephemerides()

• update_ephemeris()

• create_phase_viewer()

• add_component()

• rename_component()

• times_to_phases()

• phases_to_times()

• get_data()

• dataset (DatasetSelect): Dataset to use for determining the period.

• method (SelectPluginComponent): Method/algorithm to determine the period.

• query_for_ephemeris() Query the NASA Exoplanet Archive’s Planetary System Composite Parameters table for the planet-hosting star identified by the observation’s header key “OBJECT”, or if that fails, by the observation’s header keys for RA and Dec.

• query_result (SelectPluginComponent): The name of a planet from a NASA Exoplanet Archive query, used for adopting literature values for the orbital period and mid-transit time.

• create_ephemeris_from_query() Create an ephemeris component with the period and epoch from the planet selected from the NASA Exoplanet Archive query in query_result.
