Notes. Each profile was modelled as the sum of three Gaussians, which represent emission associated with the nebula, the primary star and the secondary star, respectively. The widths of each Gaussian, along with the radial velocity of the nebula component, were jointly fit for using all profiles, and are shown at the bottom of the table.
