            * - :py:attr:`~ansys.stk.core.stkobjects.RadiationPressure.file`
              - File containing parameters defining a ground reflection model that defines albedo and emissivity properties of the central body surface.
            * - :py:attr:`~ansys.stk.core.stkobjects.RadiationPressure.ck`
              - Coefficient of radiation pressure reflectivity of the satellite. Dimensionless.
            * - :py:attr:`~ansys.stk.core.stkobjects.RadiationPressure.area_mass_ratio`
              - Area exposed to radiation pressure (nominally along the radial direction) divided by the mass. Uses AreaPerMass Dimension.
            * - :py:attr:`~ansys.stk.core.stkobjects.RadiationPressure.include_albedo`
              - Opt whether to consider albedo effects (i.e., radiation pressure caused by sunlight reflected off the lit part of the central body).
            * - :py:attr:`~ansys.stk.core.stkobjects.RadiationPressure.include_thermal`
              - Opt whether to consider thermal radiation pressure effects (i.e., radiation pressure caused by blackbody heat radiation of the central body).
