Summary of the spectroscopic data presented in this work.

Instrument	N_spectra	Spect. range	S/N	σ_RV	RV rms	Peak-to-valley
		(μm)		(km s⁻¹)	(km s⁻¹)	(km s⁻¹)
GIANO/GIANO–B	18	0.95–2.45	72	0.036	0.130	0.384
HARPS–N	20	0.38–0.69	35	0.029	0.280	1.036
IGRINS	29	1.45–2.5	134	0.059	0.109	0.384

Notes. For each dataset we list the instrument used for the observations, the number of spectra, the spectral range, the typical S/N, the RV nominal internal error (σ_RV), the RV rms scatter, and the peak-to-valley value of the RVs.
