* correction due to proper motion (International Celestial Reference System to
Barycentric Celestial Reference System transformation)
The [k.sub.i] are called the
barycentric coordinates of k.
This is more efficient than a call to INTRC1, but requires that the triangle and
barycentric of the point be specified.
To mention only a few: relativistic effects,
Barycentric Dynamical Time, measurement of Atomic Time, clock synchronization by very-long-baseline interferometry, planetary terms in nutation (used only for arc-millisecond accuracy!), the FK5 system, laser ranging, and rotation parameters for satellites of the planets.
There are several references related to polynomial Hermite interpolation in one and several variables, including
barycentric implementations; cf.
The dual grid of a simplicial mesh can be chosen based on a
barycentric subdivision, or in some cases, based on a Delaunay-Voronoi construction [24].
The arctic boundary is shown in Figure 7 after the change to
barycentric coordinates [alpha] = a/(1 - a - b), [beta] = b/(1 - a - b).

The
barycentric coordinates of a point x [element of] [Sigma] are real numbers [[Phi].sub.i] with
The other relies on a
barycentric formulation which is new and very suitable for numerical evaluations.
