  4. Diameter [m]

  5. m/A [kg/m2]

  6. a [km]

  7. e

  8. i [deg]

  9. RAAN [deg]

  10. AoP [deg]

  11. M [deg]

Parameters

  • input_file (str) – Path to the input MASTER file.

  • sort (bool) – If True sort according to diameters in descending order.

  • mjd0 (float) – The epoch of the catalog file in Modified Julian Days.

  • propagator (PropagatorBase) – Propagator class pointer used for space_object.SpaceObject.

  • propagator_options (dict) – Propagator initialization keyword arguments.
