public class EphemerisPvHermite extends AbstractBoundedPVProvider
This class extends AbstractBoundedPVProvider which implements
PVCoordinatesProvider and so provides a position velocity for a
given date. The provided position velocity is based on a Hermite interpolation in a given position velocity
ephemeris.
The interpolation extracts position, velocity and eventually acceleration from the ephemeris depending on the number of sample points and the date to interpolate. Points extraction is based on an implementation of the ISearchIndex interface. This implementation should be based on a table of duration created from the date table with the duration = 0 at the first index.
