Fig. 6.
Top: optical spectra from LT:SPRAT and NTT:EFOSC2. The phases are with respect to maximum light. The inset highlights some narrow features in the spectra that remain unidentified. Middle and bottom: raw VLT:X-shooter UV and optical spectra (light grey) and binned to 5 Å (black). The outer edges of the UVB and VIS arms have been omitted from the binning process due to excess noise. Note that the region between 5200 and 5800 Å is the inner boundary between the UVB and VIS arms. Due to the low signal to noise ratio (S/N) any features here are unlikely to be real.
