Best-fit Burrows model (blue spectrum) and all other Burrows models with P > 0.05 (yellow, smoothed for easier visibility). a) Range of accepted models when only JHK_s photometric data are fit. b) The mid-infrared spread of acceptable model fits is strongly reduced when all 1–5 μm photometric points are taken into account. c) Fits of the K-band spectroscopy (red). d) Simultaneous fit to all JHK_sL′BrffM_s photometry and K-band spectroscopy.
