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.
