SMN 13 ZZ Tau. Sfr2003 astrometry for 1995.081 and 1996.124 was based on
interpolation of one-dimensional data by Simon. Smn1996a
The first ZZ Tau orbit by Schaefer et al. (2006) gives range 1994-1999 Sfr2006
for T, 0.35-0.88 for e, 115-134 for i, 111-129 for Omega, 268-336 for
omega. Values of P and a are lower limits. The second orbital
solution includes a lunar occultation measure by Simon et al. (1995). Smn1995
Assuming a distance of 140 pc, Schaefer et al. (2014) derive a total
mass of 0.83 +/- 0.16 Msun. Sfr2014
