U to V band of the X-shooter spectra. Black, light blue, and gray lines are for epochs 7, 8, and 9, respectively. Y-axis units are erg cm⁻² s⁻¹ Å⁻¹; X axis units are Å. The epoch 9 spectrum was cut below ∼3800 Å, because no signal was evident there in the 2D frame. The epoch 8 and 9 spectra are almost identical in the continuum (where present), with the epoch 9 spectrum having stronger molecular bands in emission. Bracketed numbers refer to the Moore’s multiplet identification (Moore 1945).
