**Table 1:** Orbital parameters for single-lined systems. Columns 2-9: Parameters of the orbital solution. P: revised period, $T_{\rm tr}$ (OGLE): epoch of the transit (fixed), $P_{\rm OGLE}$ : original OGLE period, $T_{\rm p}$ : epoch of periastron, w: omega angle, K: orbital semi-amplitude, V₀: systemic velocity, e: eccentricity. Column 10: projected rotation velocity from the cross-correlation function.
