Result of spectrum fitting with single templates. The single template 2M2057−02 (blue line) is the best fit to the SpeX spectrum of DE0823−49 (black line) both for the “young” and “all” set of templates. At the top of the panel, the spectral ranges considered for the fit are indicated by grey horizontal bars, where telluric water absorption dominates the gaps. The inset shows a close-up of the H-band region. The residual spectrum is shown in grey.
