Top: S CrA N CRIRES+ reduced and telluric-corrected spectra in all available L- and M-band settings (colors). The wavelength separation of the orders can be seen; for instance, the M4519 (red) filter shows five orders (two orders fall in the telluric absorption gap from 4.2 to 4.5 μm). Note that between 3.4 and 4.2 μm L- and M-band filters overlap. The sky transmission is shown in black, for reference. Middle: The signal-to-noise ratio for each filter, order, and detector in the S CrA N spectra. Bottom: The combined L- (blue) and M-band (red) spectra for S CrA N after flux calibration and continuum subtraction. Prominent emission features are labeled. Regions where the atmospheric transmission is below 50% are masked. The gray lines indicate the ±3σ regions for reference.
