Radial velocities of the program stars by STELLA. The data for stars with periodic variations are plotted vs. the phase. The others are plotted vs. the heliocentric Julian date. If a binary and an orbital solution were obtained then the lines represent the orbital elements. If an SB2 solution was obtained, the closed and open symbols refer to the primary and secondary component, respectively. The horizontal dashed line is the systemic velocity. a. β Aur, b. ε Aur, c. η Aur, d. θ Aur, e. ν Aur, f. ι Aur, g. κ¹ Cet, h. V711 Tau.
