Benchmark model spectrum (orange) overplotted on the SED data for Tau 042021, normalised to the observed average flux in the NIRSpec range. Blue photometric points are taken from Table 4 of Duchêne et al. (2024). Orange symbols correspond to the ≤ 2.2 μm photometric points adjusted by a factor to match the JWST flux, taking into account the known potential variability of the source (see text for details). Error bars (3σ) are given for the long wavelength photometric points from Spitzer/MIPS, Herschel/PACS and Herschel/SPIRE, retrieved from published point source catalogues.
