Least-χ² fits to the SED of 2M1115 with DRIFT-PHOENIX, BT-Settl-AGSS2009 and AMES-Dusty atmospheric models. The overall best fit with the minimum χ² corresponds to DRIFT-PHOENIX model at T_eff = 1800 ± 50 K, log(g)= 4.0 ± 0.25 and metallicity= 0.3 ± 0.15. The SDSS DR12 spectrum for 2M1115 is also shown, along with its flux uncertainty (grey shaded region). Note that the flux in the WISE W4 band is a 2σ upper limit, denoted by the red downward-pointing arrow, and is not included in the fitting process. The unWISE catalogue (Lang et al. 2016; see https://unwise.me/photsearch/) however reports a W4 detection consistent with this upper limit.
