`DRAG_AREA`	Drag Area - the cross-sectional area of the spacecraft assumed perpendicular to the direction of motion, used for atmospheric drag calculations.
`SRP_AREA`	Solar Radiation Pressure (Spherical) Area - the cross-sectional area of the spacecraft assumed perpendicular to the direction of solar radiation, used for solar radiation calculations.
`DRY_MASS`	Dry Mass - the mass of the spacecraft exclusive of propellant.
`FUEL_MASS`	The mass of the spacecraft propellant.
`FUEL_DENSITY`	The density of the fuel tank.
`TANK_PRESSURE`	The fuel tank pressure.
`TANK_TEMPERATURE`	The temperature of the fuel tank.
`CR`	Solar Radiation Pressure (Spherical) Coefficient (Cr) - the reflectivity of the spacecraft used for solar radiation pressure calculations, where 2.0 is fully reflective and 1.0 is not reflective at all.
`CD`	Drag Coefficient (Cd) - the dimensionless drag coefficient associated with the drag area.
`CK`	Radiation Pressure (Albedo/Thermal) Coefficient (Ck) - the reflectivity of the spacecraft used for central body radiation pressure (albedo / thermal pressure) calculations, where 2.0 is fully reflective and 1.0 is not reflective at all.
`RADIATION_PRESSURE_AREA`	Radiation Pressure (Albedo/Thermal) Area - the cross-sectional area of the spacecraft assumed perpendicular to the direction of central body radiation, used for central body radiation (albedo / thermal pressure) calculations.
