Radial velocity curves for J093010A. The primary’s measurements are indicated by squares, the secondary by diamonds and the third component by triangles. Data from Koo et al. (2014) is in fainter print (orange and light blue in the online version of the paper) and our new results are in bold print (red, dark blue and green). Phase-folding uses Koo et al.’s primary minimum time of HJD 2 456 346.78443 and our optimum period. PHOEBE model fits are overplotted (solid black curves) and the location of the modelled system velocity is shown by the dashed line.
