Notes. All radial velocities are given in units of kms−1. We use the following notation: vR,Tell is our measured RV of the tellurics; vR,BC is the RV of the observatory towards the target vR,⋆ is the RV of the star as measured by GAIA; vR,P is our measured RV of the planet; ΔvR,P⋆ is our final measurement of the RV of the planet relative to its star (if the stellar RV is not available, then ΔvR,P⋆ indicates the RV of the planet relative to the solar barycentre); finally, the superscript denotes which molecular spectral template (CO or H2O) was used. The final values are obtained using the formula ΔvR,P⋆ = vR,P − vR,Tell − vR,⋆ + vR,BC. The last column indicates the result of a Welch’s t–test between the bootstrap samples obtained from the RV measurement using the spectral templates of CO and H2O. The further a t–test value is from zero (positive or negative), the larger is the inconsistency between the RV measurements performed with the CO and H2O templates.
