High resolution UVES spectrum at −5 d. Top left: blue region (3700−4670 Å) dominated by Fe II lines. The insets show blow-ups of the Ca II H&K region (centred at λ3933.66) and the Fe II (multiplets 37 and 38; centred on the λ4534.17 line). Top right: region between 5840 Å and 6270 Å with Na ID and Fe II lines (multiplets 46 and 74). The inset shows the narrow Na ID interstellar doublet centred on the λ5889.95 line; the upper red line is the Milky Way component; the lower black line one is the host galaxy ones). Bottom left: Hα region, including also some Fe II lines. The blow-up shows a detail of the narrow Hα P Cygni. Bottom right: 8420−8690 Å region with insets showing a detail of O I λ8446.46 (left) and Ca II λ8662.14.
