LBT/LUCIFER1 J- (left) and H + K-band (right) spectra of ULAS J0954+0623 (top), ULAS J1204−0150 (centre), and ULAS J1152+0359 (bottom). Target spectra (black) were smoothed for the comparison with the lower-resolution (R ~ 120) template spectra (red) of T5-T6.5 dwarfs from Adam Burgasser’s SpeX Prism Spectral Libraries. Original references for the T5/T6 and T5.5/T6.5 template spectra are Burgasser et al. (2004) and Burgasser et al. (2008), respectively.
