AC 15	99 Her.
	Identification of the ascending node is not very certain.	Hei1972
	Kennedy et al. (2012) derive a system mass of 1.4 Msun, using the van
	Leeuwen(2008) distance 15.64pc. Using the spectroscopic mass function	VlF2008
	of Abt & Willmarth (2006), this yields component masses 0.94 and 0.46	AbH2006
	Msun for A and B, respectively.	Knd2012
	AB: Malkov et al. (2012) derive dynamical, photometric, and
	spectroscopic masses 1.73 +/- 0.23, 1.85, and 1.13 Msun, respectively.	Mlk2012
