Notes. From left to right: the observing night, the number of observed spectra, the exposure time, the average S/N across the selected spectral range (1082.49–1085.5 nm), the uncertainty on the mid-transit time for the observed transits calculated as σTc=σT02+n2σP2${\sigma _{{{\rm{T}}_{\rm{c}}}}} = \sqrt {\sigma _{{{\rm{T}}_0}}^2 + {n^2} * \sigma _{\rm{P}}^2} $ (where T0 and P are the mid-transit time and orbital period in the adopted ephemerids reported in Table A.1 and n is the number of orbits between times Tc and T0), and flag for significant telluric overlap/possible stellar activity issues.
