The last paragraph of my original post is incomplete. It should read as follows: "Some of these data occur near the predicted periastron passage in the interferometric orbit (P=10.583). Analysis of the radial velocity data, especially with regard to that orbit, is continuing. The probability of this apparent period being due to motion in a binary star seems extremely small (to say the least): The value for a sin i places the companion inside the primary."
