  Data Source Descriptions
  ========================
 
    ELEMENTS-PLANET
    The 1989 Astronomical Almanac, page E3.
 
    MAGMOMENT-PLANET
    C.T. RUSSELL, CH. 5 IN GEOMAGNETISM, VOL. 2 (ACADEMIC PRESS)
 
    MEANSOLARDAY-PLANET
    Derived from three other target constants catalog elements:
    REVOLUTION_PERIOD (RP), SIDEREAL_ROTATION_PERIOD (SRP), and
        ROTATION_DIRECTION_TYPE (RDT)  as follows:
        If RDT = PROGRADE, then MSD = (RP * SRP)/(RP - SRP).
        If RDT = RETROGRADE, then MSD = (RP * SRP)/(RP + SRP).
 
    ORBSEMIMAJAX-PLANET
    Derived from data from The 1989 Astronomical Almanac,
    converting Mean Distance on page E3 to km using the value
    for Unit Distance found on page K6.
 
    PERIARGANG-PLANET
    Derived from data from The 1989 Astronomical Almanac as
        LAN-LP, where LAN is the Ascending Node Longitude and LP is
    the Longitude of Perihelion, both from page E3.
 
    PHYSICAL-PLANET
    The 1989 Astronomical Almanac, page E88.
    The 1989 Astronomical Almanac, page K6.
 
    RADIUS-PLANET
    Taken or derived from REPORT OF THE IAU WORKING GROUP ON
    CARTOGRAPHIC COORDINATES AND ROTATIONAL ELEMENTS OF THE
    PLANETS AND SATELLITES, 1988 as follows:
    Given Mean Radius (MR), Equatorial Radius (ER), and Polar
    Radius (PR), then this catalog defines the following:
          A_AXIS_RADIUS        = ER
          B_AXIS_RADIUS        = ER
          C_AXIS_RADIUS        = ER
          FLATTENING           = (ER - PR)/ER
 
    REVPER-PLANET
    Derived from data from The 1989 Astronomical Almanac as
    360/n where n is the Daily Motion from page E3.
 
    ROTATION-PLANET
    The 1989 Astronomical Almanac, page E87.
    The Astronomical Almanac, 1989, page C3.
 
    SURFGRAV-PLANET
    Derived from data in THE 1989 ASTRONOMICAL ALMANAC and the
    1988 REPORT OF THE IAU WORKING GROUP ON CARTOGRAPHIC
    COORDINATES as (G * MASS)/(MR * MR) where MR is MEAN RADIUS
    from this catalog, MASS comes from page E88, and the
    gravitational constant, G, comes from page K6.
