Orbital solution for σ Sco as derived by Mathias, Gillet & Crowe (1991, indicated as M1991), Pigulski (1992, indicated as P1992), and North et al. (2007, indicated as N2007). Errors are given in parentheses in terms of last digits. Subscripts 1 and 2 refer to the primary and secondary component, respectively.
