COLUMNS FORMAT DESCRIPTION DEFAULT VALUE & UNITS
1-6 A6 PLMOON - Requests application and or adjustment of
planetary moon GM. This option can be selected for up
to 5 moons. The moons must be orbiting the central
body of the run. This option is not to be used for the
following central bodies: Earth, Earth's moon, and the Sun.
Since, the moons selected by this option are not contained
in the JPL planetary ephemeris, the user must supply a
Keplerian ephemeris for each of the moons. The format and
file names for the ephemeris are described below.
12-14 I3 Indicates the moon for which this perturbation NO DEFAULTS
should be applied.
Body numbers are in the following format: C0M
C - is central body of this run:
1 = Mercury
2 = Venus
4 = Mars
5 = Jupiter
6 = Saturn
7 = Uranus
8 = Neptune
9 = Pluto
M - number of this moon (up to 5 moons can be specified)
Example: Mars moon numbers could be:
Phobos - 401
Deimos - 402
25-44 D20.8 Universal gravitational constant times the mass M**3/s**2
of the moon
Default values exist for the following bodies:
Phobos - 401 - 720000.0 M**3/s**2
Deimos - 402 - 120000.0 M**3/s**2

MOON EPHEMERIS INFORMATION:
For each moon specified in a run, an ephemeris must be supplied to the
GEODYN IIE portion of the program. The file names used in the IIE setup
have the following construction:
MOON EPHEMERIS FILE NAME = MON###
where ### is the particular moon number specified on the PLMOON card.
Thus, for a typical Mars run with 2 PLMOON cards (one for PHOBOS - 401 and
one for DEIMOS - 402) a moon ephemeris needs to be supplied for each moon.
An example of the file names follows:
MON401 - IIE ephemeris file for Mars moon #1 (PHOBOS)
MON402 - IIE ephemeris file for Mars moon #2 (DEIMOS)
The moon ephemeris file has the following format:
HEADER RECORD -> F10.2 -> constant bias to be applied to mean anomaly values.
DATA RECORDS -> 1X, I6, I5, F10.6, F16.3, F15.11, F16.9, 3F17.9
WORD #1 -> I6 -> YYMMDD
WORD #2 -> I5 -> 0HHMM
WORD #3 -> F10.6 -> SECONDS INCLUDING FRACTION
WORD #4 -> F16.3 -> SEMI-MAJOR AXIS (meters)
WORD #5 -> F15.11-> ECCENTRICITY
WORD #6 -> F16.9 -> INCLINATION (degrees)
WORD #7 -> F17.9 -> LONGITUDE OF THE ASCENDING NODE (degrees)
WORD #8 -> F17.9 -> ARGUMENT OF PERIGEE (degrees)
WORD #9 -> F17.9 -> MEAN ANOMALY (degrees)
IF CARD OMITTED: Planetary moon perturbations will not be applied.
