ES 2603	SZ Cam
STF 485	The classification is from Chocol (1980 Bull. Astron. Inst. Czech. 31,
CHR 209	321). The discovery of speckle companion CHR 209 Ea,Eb with a period
WSI 20	of some 60 y confirms the third body model advocated by Mayer et al.
HZG 2	(1994 A&A 288, L13) based on the appearance of the spectrum and
HLM 3	variations in the time of light curve minimum (they suggest a third
	body period of 50.7 y). Another light curve solution is given by
	Harries et al. (1998 MNRAS 295, 386). The B component was also
	observed and appeared to be single. Classification of the B component
	is from the WDS.	Msn1998a
	This complex multiple system has had numerous identification errors
	due to various difficulties. The diagram of Lewis in his catalog of	L__1906b
	the Struve pairs, which seemed a good first step, was hampered by the
	quadrant error of the pair he designated Ca. This quadrant error was
	repeated in the ADS, IDS, and in earlier editions of the WDS. In the
	ADS (where this pair is listed as #2984, but note that #2989 is part
	of this system, too) the errors multiplied. The pair Holmes AF (WDS
	designation HLM 3AF) is apparently the same as STF 485Ac. Inspection
	of scanned images of this region of the sky have allowed the
	Hertzsprung pairs (HZG 2) whose components are given within
	quotation marks in the ADS to be identified. Of the HZG pairs, the
	"CD" pairing is the same as STF 484AC and the "CE" pairing is the
	same as STF 484AB. The ADS note to the "AJ" pairing of HZG 2 is a
	typographical error. The correct position angle is 77 degrees, which
	corresponds to the AD (now AO) pair. Below outlines the changes from
	the WDS 2001.0 to the current version.

CHR 209	Ea,Eb: The primary of this pair is the Beta Lyrae-type O9/B0 eclipsing
	system SZ Cam, with a period of 2.698d. The Gorda et al. (2007) orbit	Grd2007a
	is based on changes in the period of SZ Cam to determine P, omega, e,	Grd2007b
	and T, and speckle measures to derive i, Omega, and a. They derive a
	distance of 1125 +/- 135 pc, which exceeds by 30% the 800pc distance
	to the open cluster NGC 1502; they conclude that SZ Cam is not a
	member of the cluster. The mass of the eclipsing pair (Ea) is 28.5
	+/- 0.5 Msun, that of the third body (Eb) 23.4 +/- 2.4 Msun.
	Eb is also a close binary.
