boinor.constants.general ======================== .. py:module:: boinor.constants.general .. autoapi-nested-parse:: Astronomical and physics constants. This module complements constants defined in `astropy.constants`, with gravitational paremeters and radii. Note that `GM_jupiter` and `GM_neptune` are both referred to the whole planetary system gravitational parameter. Unless otherwise specified, gravitational and mass parameters were obtained from: * Luzum, Brian et al. “The IAU 2009 System of Astronomical Constants: The Report of the IAU Working Group on Numerical Standards for Fundamental Astronomy.” Celestial Mechanics and Dynamical Astronomy 110.4 (2011): 293–304.
