Spectrum observed in Visit B_fuv in the region of the O I triplet (average of the FP₄ over the visit, in black). Blue spectra show the stellar lines corrected for contamination using airglow templates (red profiles). They are in good agreement with the airglow-free spectra (average of the FP_1,2,3 over the visit, in orange). The stellar lines have been centered in the star rest frame (dashed black line).
