Broadening function power diagram of IO Aqr’s HARPS spectrum taken 2010 September 29 (JD = 2 455 468.5) during full astronomical night with the moon well below horizon. The low-temperature template (Teff = 3950 K) was used to highlight the signal from the third body in the spectrum – the small bump in the middle. The paraboloid curves are rotationally broadened fits to the BF of the primary (right) and the secondary (left), and the continuous vertical lines are the resulting radial velocities of the three stars.
