Notes. Note that for both campaigns, there are no observations for one night due to bad weather. n is the total number of spectra, ⟨ S/N ⟩ indicates the mean signal-to-noise ratio, ΔT indicates the total time between the first and last observations, Δt provides the average time interval between two consecutive exposures of a same night. The last two columns indicate the natural width of the peaks in the periodogram Δνnat = ΔT-1 and νmax = (2 ⟨ Δt ⟩ )-1 provides an indication of the highest frequency that can possibly be sampled with our time series.
