public class CoordinateSystemTerm
extends LongValuedIIRVTerm

1-character representing the coordinate system associated with the state variables.

Valid values:

• 1 = Geocentric True-of-Date Rotating
• 2 = Geocentric mean of 1950.0 (B1950.0)
• 3 = Heliocentric B1950.0
• 4 = Reserved for JPL use (non-GSFC)
• 5 = Reserved for JPL use (non-GSFC)
• 6 = Geocentric mean of 2000.0 (J2000.0)
• 7 = Heliocentric J2000.0

Since:

13.0
