VLT/X-shooter spectrum of USco1556 B in the NIR band (black) overplotted with USco known members (coloured) obtained with Gemini North GNIRS by Lodieu et al. (2008), for comparison. The X-shooter spectrum has been smoothed using a Gaussian kernel. GNIRS spectra were also degraded by Gaussian convolution to match the same spectral resolution. The spectra have been normalised in the H-band region (wavelength range ~1.5–1.8 μm), and shifted by a constant for clarity. Zones affected by atmospheric telluric bands are marked as grey bands. The most prominent spectral features are labelled.
