Examples of broadening function curves. The orbital velocity of the primary components is marked with a blue line and that of the secondary components with a magenta line. The systemic velocity is indicated by the dashed line. (a) BF Vel phase 0.28, 2020 Nov. 1, exp. time = 240 s. (b) BF Vel phase 0.73, 2020 Nov. 2, exp. time = 240 s. (c) RR Lep phase 0.25, 2020 Dec. 1, exp. time = 240 s. (d) RR Lep phase 0.76, 2020 Nov. 3, exp. time = 420 s.
