SKW 1	Aa,Ab. Primary of the Herbig Ae/Be pair LkHa 198. A family of possible	SKW2005
	orbits are calculated, based on various choices for initial parameters
	(luminosities, component masses, etc.). Neither a" nor T0 was
	provided. a" was calculated from other published parameters and T0 was
	determined by trial and error with comparison to their Figure 3.
