WDS 05025+4105 MKT 6 (Saclateni) : NOTES

discov_num	notes	refcode
MKT 6	zet Aur = Saclateni. The first of the zeta Aurigae-type binaries (K4IB
	+ B5V). This object was misidentified as rho Aur by McAlister (1978).	McA1978c
	Hipparcos astrometric solution adopted some elements from the orbit of	HIP1997d
	Wright (1970).	Wri1970
	Bennett et al. (1996) orbit is combined solution, using astrometry	MkT1996
	from the Mark III interferometer, spectroscopy from HST Goddard High
	Resolution Spectrograph, and published photometry to determine masses,
	radii, etc. Positions of component stars on theoretical H-R diagram
	are compared to current evolutionary models.
	Errors to individual measures are given as "error ellipses"; these
	values are tabulated below, together with filters used. The columns
	include date (BY), major and minor axes of the ellipse (in mas),
	ellipse orientation (deg), and filter effective wavelengths (nm):
