HARPS RV data of GJ 143 phased to the best-fit period of P_b = 35.589 d. Blue data points show the pre-fiber upgrade data, while red data points represent post-fiber upgrade data. After fitting for the mutual RV offset, these data sets are consistent with each other. The orbital solution is consistent with the TESS transit event. The RV uncertainties include the estimated RV jitter, which was quadratically added to the error budget.
