def pa_comet_data.get_comet_data_elliptical | ( | comet_name | ) |
Get data for elliptical comet. Example, retrieving orbital period of Halley: get_comet_data_elliptical("Halley")['Period'] Arguments: comet_name -- Name of comet, e.g., "Halley" Returns: A dictionary object with the following elements: Epoch -- Epoch of the perihelion. Peri -- Longitude of the perihelion. Node -- Longitude of the ascending node. Period -- Period of the orbit. Axis -- Semi-major axis of the orbit. Ecc -- Eccentricity of the orbit. Incl -- Orbital inclination.
def pa_comet_data.get_comet_data_parabolic | ( | comet_name | ) |
Get data for parabolic comet. Example, retrieving longitude of the ascending node of Kohler: get_comet_data_parabolic("Kohler")['Node'] Arguments: comet_name -- Name of comet, e.g., "Kohler" Returns: A dictionary object with the following elements: EpochPeriDay -- Epoch of the perihelion (day) EpochPeriMonth -- Epoch of the perihelion (month) EpochPeriYear -- Epoch of the perihelion (year) ArgPeri -- Longitude of the perihelion (degrees) Node -- Longitude of the ascending node (degrees) PeriDist -- Distance at perihelion (AU) Incl -- Orbital inclination (degrees)
