Phase-folded RV data of J02222+478 (GJ 96). Left. SOPHIE (green squares) and CARMENES VIS (blue circles) phase-folded to a period of 73.94 days. The planetary Keplerian signal (dashed green line) proposed by Hobson et al. (2018) is based on the SOPHIE data alone and disfavoured by the CARMENES measurements. Right same as the left panel, but phase-folded to the periodicity of 28.3 days, which is most likely associated with stellar activity.
