Distribution of different orbital elements (Upper left: argument of periastron ω; upper right: eccentricity e; lower left: semi-amplitude K of the orbital RV variations; and lower right: projected semi-major axis a sin i) versus orbital period P_orb for Cepheids with the orbits determined here. SB1s with newly reported orbits in this study are plotted using open squares, while VELOCE orbital estimates of SB1s with literature-known orbits are plotted in open circles. Symbols with double boundaries highlight V+L orbits determined using VELOCE and zero-point corrected literature RVs. R Cru, SY Nor and YZ Car are absent in the top left panel due to insignificant eccentricity.
