While EphemerisFile.EphemerisSegment.getCoordinates()
always returns position, velocity, and
acceleration the return value from this method indicates which of those are in
the ephemeris file and are actually valid.

EphemerisFile.EphemerisSegment.getAvailableDerivatives()
indicates if the velocity or accelerations were
specified in the file. Any position, velocity, or acceleration coordinates that
are not specified in the ephemeris file are zero in the returned values.public AbsoluteDate getStart()

The date returned by this method is equivalent to
getPropagator().getMinDate()
.
