Remarks: (1) this work; (2) Reimers et al. (1988); (3) combined solution (see text); (4) SS Lep: M4III + accreting A1 star (Welty & Wade 1995). Verhoelst et al. (2007) shows, from interferometric measurements of the M-giant radius, that the giant fills its Roche lobe (see also Paper III); (5) possibly a triple system, formerly a radial-velocity standard star; Duquennoy & Mayor (1991) found a preliminary 509 d period for the inner pair, but the orbital nature of the short-period variations is questionable (Sect. 3.3.2); (6) HD 190 658 = V1472 Aql = HIP 98 954: semiregular or most likely eclipsing or ellipsoidal variable with P = 100.37 d, almost exactly half the orbital period (Samus 1997). Orbital elements from Lucke & Mayor (1982). A (physical?) companion is present at 2.3$^{\prime\prime}$ (Frankowski et al. 2007; Tokovinin 1997).
