(not-comparable) Relating to a photocentre
We find that the photocentric orbit has a period P#61;633.0#92;pm 1.7 days, somewhat longer than previous results, with eccentricity of e#61;0.42#92;pm 0.03, and we estimate that the semi-major axis of the orbit of the primary is a#95;1#92;approx 0.32 AU, consistent with previous results.
