COLUMNS FORMAT DESCRIPTION DEFAULT VALUE & UNITS
1-6 A6 REFSYS - Specifies the coordinate system
of integration and the number of arc
iterations.
7-8 I2 Maximum number of arc iterations during 1
the first global iteration.
9 I1 Minimum number of arc iterations during 1
the first global iteration.
10 I1 Maximum number of arc iterations during 1
global iterations after the first.
11 I1 Coordinate reference system 0
0 True of reference date and time
1 Mean of J2000 [1]
21-26 I6 Year,month,day of reference date (YYMMDD). 0
27-30 I4 Hour,minute of reference time (HHMM). 0

NOTE:
[1] The DE200 Ephemeris is needed when the J2000 reference system
is selected. No reference date is needed in cols. 21-40 if
J2000 is selected.
