Top panel: Fourier transform for the radial velocities of EPIC 246429212, as obtained from SOAR spectra. Bottom panel: values of χ2 for orbital solutions calculated at each period, assuming a circular orbit. The dashed red line marks the photometric period. The radial velocities do not constrain the period well, but a solution with low χ2 is possible near the photometric period.
