The residual RV after removing the 290 d periodicity. The periodogram in the upper panel shows two peaks at 6.95 d and 1.16 d. The 1.16 d is identified as a harmonic of 6.95 d (1/1.16 + 1/6.95 = 1.0). The lower panel shows the phase folded RVs with a period of 6.95 d. The solid line shows a Keplerian fit for the residual RV variation.
