Mars

The parameters of the Martian ellipsoid were obtained from [Ardalan2009]:

>>> from boule import MARS
>>> print(MARS)
Ellipsoid(name='MARS', ...)
>>> # Flattening
>>> print("{:.5f}".format(MARS.flattening))
0.00523
>>> # Semimajor axis
>>> print("{:.0f}".format(MARS.semimajor_axis))
3395428
>>> # Semiminor axis
>>> print("{:.0f}".format(MARS.semiminor_axis))
3377678
>>> # Geocentric gravitational constant (GM)
>>> print("{:.7e}".format(MARS.geocentric_grav_const))
4.2828372e+13
>>> # Angular velocity
>>> print("{:.7e}".format(MARS.angular_velocity))
