WDS 00174+0853 A 1803 AB : NOTES

discov_num	notes	refcode
A 1803	Too close 1932, 1946-47, 1965-72. Modern measures show a close
	approach about 1985. While both 18- and 36-year period orbits
	have been calculated for this pair, Griffin (Docobo, private
	communication) determined spectroscopically that the shorter-period
	high-eccentricity orbit is the correct one.
	The measure reported for 1976.622 is spurious and has been deleted
	from the catalogs.	McA1982b
	Large and irregular residuals preclude the correction of an orbit.	Tok1985
	AB: Malkov et al. (2012) derive dynamical, photometric, and
	spectroscopic masses 0.02 +/- 0.02, 1.48, and 1.13 Msun, respectively.	Mlk2012
STF 22	AB,C: H 2 50.	MEv2010
