MIRI/MRS (this work), NIRSpec/PRISM, and NIRSpec/G395M Luhman et al. (2024) spectrum of WISE 0855 from 0.8 to 22 µm. Panel a: NIRSpec/PRISM data (in red) from 0.8 to 2.2 m. Panel b: NIRSpec/G395M (in green) and MIRI/MRS data (in blue) from 2.2 to 22 m. Panels c and d: Overlap between the three datasets from 3.5 to 5.4 µm and the ammonia feature from 8.0 to 13.0 µm, respectively. The most dominant absorbing species are presented above the spectrum in various colors. For better visualization he data was binned to a resolution of R = 1000 for MIRI/MRS and NIRSpec/G395M andR= 100 for NIRSpec/PRISM.
