Flux-calibrated integrated spectrum of the BCG Haro 14. (a) Spectrum in the whole observed wavelength range (4750–9300 Å). Shaded bars mark spectral windows heavily contaminated by telluric lines which were excluded from the fitting of the stellar component. The 5800–5950 Å gap corresponds to the spectral area masked out due to the AO lasers. Bottom panels: spectral regions of particular interest, with prominent lines labeled. (b) Zoom into the 4750–5100 Å wavelength region, with the pronounced absorption wings around Hβ clearly resolved. (c) Zoom into the 6250–6800 Å spectral region. (d) Zoom into the region of 9050-9150 Å.
