Table 3: Logbook of the spectroscopic observations of HD 92024. Dates, incl. Julian date (=HJD-2 400 000), indicate start of night in UT. Column 3 lists the observers: Sterken (S), Hensberge (H) and Freyhammer (F). N is the number of spectra obtained that night, $\Delta t_{\rm exp}$ is the mean integration time (s), "Ins'' indicates instrument used (FEROS or ECHELEC) and S/N denotes the range of signal-to-noise at 4500 Å. The last column gives the orbital phase interval covered that night.
