NIRSpec spectrum of UHWJ247.95-24.78 overplotted with the three best-fitting photospheric models reddened and scaled by the corresponding AV and radius as indicated. The wavelength range considered for the comparison is highlighted by the shaded region. We find that the object fits best with the model spectra for an effective temperature of 1900 K and AV of 3 mag.
