   • 1996, Roger Peyret, editor, Handbook of Computational Fluid Mechanics, Academic Press, page 9:

     Note that least-square discretizations are also equivalent to making the convection terms elliptic; another way to ‘elliptize’ convection was derived from the Lax—Wendroff scheme by Lerat et al. (1982).

     The basic configuration was optimized for a 10 arcmin FoV at a Cassegrain focus issued from a four-segment spherical primary obtained by replication, a spherically polished secondary elliptized by partial vacuum (g=1) and a doublet-lens corrector.

     Thus a unified approach to both problems suggests itself. Following an idea of R. Picard (1985) we do it in such a way that one operator structures the null space of the other. Thus the operators mutually ‘elliptize’, simplifying the presentation.

     Although in almost all cases the orbits of the inner planets should remain within a certain range of distances from each other; in a "probability" estimated (in the models) at a few%, it is possible that the orbits elliptize enough to intersect and cause a catastrophic destabilization of the orbits of the inner planets.
