Abstract

After the publication of the article, it was brought to our attention that the quoted uncertainties for several of the orbital elements listed in Table 7 seemed unrealistically small. A comparison of orbital fits made with and without the RV data demonstrated that, in particular, the original uncertainty estimates for the period and epoch were erroneous. A new, simultaneous model fit to the astrometric and RV data was performed and the results are given in a revised Table 7 below. Other than correcting an arithmetic error in the calculation of the value for the epoch and correcting the number of significant digits given for the eccentricity and epoch, the parameters have not changed (only uncertainties) but we now list only the final values for the period and epoch from the simultaneous astrometry and RV fit. The uncertainties of the systemic velocity, RV semiamplitude of the primary, and masses remain the same. We note that our values for the semimajor axis, eccentricity, and inclination are consistent with those of Andrade (2006) within the latter’s larger uncertainties (listed in Henrichs et al. 2013), while that for the orbital period is significantly smaller than those quoted by either Andrade (2006) or Henrichs et al. (2013). (Table Presented).
