    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.
