RV drift corrections determined from pressure variations (Eq. (1)) against the corrections determined via simultaneous drift corrections based on interlaced ThAr spectra. The discretization of the results is due to the single-decimal precision with which the atmospheric pressure is recorded in the FITS headers. The black dotted line shows the equality Δυ(ΔP) = Δυ_Th, whereas the blue, red, and green lines are the best linear fits to the Coralie07, Coralie14, and combined Coralie distributions, as quantified in the legend.
