Top panels: VLT X-Shooter optical (left) and near-infrared (right) spectra corrected for telluric lines for the L dwarf component of Luhman 16AB. Bottom panels: same but for the T component of Luhman 16AB. Overplotted as red lines are spectral standards downloaded from the SpeX archive and Sandy Leggett’s webpage: 2MASS J15074769−162738.6 (L5–L5.5; Reid et al. 2000; Dahn et al. 2002; Kirkpatrick et al. 2000; Knapp et al. 2004), 2MASSs J0850359+105716 (L6; Kirkpatrick et al. 1999), 2MASSI J0103320+193536 (L7; Kirkpatrick et al. 2000), 2MASS J16322911+1904407 (L7.5; Leggett et al. 2002; Geballe et al. 2002), 2MASS J03105986+1648155 (L9; Kirkpatrick et al. 2000; Burgasser et al. 2006; Reid et al. 2001; Leggett et al. 2002; Geballe et al. 2002), SDSS J04234857−0414035 (T0; Leggett et al. 2000; Geballe et al. 2002; Cruz et al. 2003; Burgasser et al. 2006), SDSS J08371721−0000180 (T1; Leggett et al. 2000, 2002; Burgasser et al. 2006; Kirkpatrick et al. 2008), and SDSSp J125453.90-012247.4 (T2; Leggett et al. 2000; Burgasser et al. 2004). All optical and near-infrared spectra are normalised at ~840−860 nm and 1300 nm to ease the comparison.
