Notes. All RV measurements are kept in the analysis because weather degradations did not induce significant RV changes (see text). BJD, seeing and airmass values are given at mid-exposure.

(1)

RVO2 is the RV derived from the cross-correlation of the spectra with a telluric O2 mask.

(2)

The SNR is per pixel at ~550 nm.

(3)

The mid-exposure is calculated from the photometer count of the detectors and weighting by the spectral information between the blue and the red arms.
