Top: eccentricity fitted by SBCM (Morbey & Brosterhus 1974) using the RVs measured on the theoretical, tidally-perturbed line profiles of m1 as a function of the longitude of periastron. The calculations were all performed with e = 0.1. The error bars are the uncertainties given by the RV curve fitting routine. Bottom: the crosses are the fitted eccentricities shown in the top panel after subtracting the actual value e = 0.1. The squares are the historic e values quoted by Shobbrook et al. (1972) and the values we have derived in this paper, after subtracting the mid-point value e = 0.125. The value in parenthesis is the one given in Herbison-Evans et al. (1971). The error bars represent the corresponding quoted uncertainties.
