    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.
