Spitzer IRS spectra of emission lines detected in TDG‐S (histogram). The lines were fit with a Gaussian profile combined with a first‐order polynomial fit to the continuum (solid line). The lines are from IRS‐SH/LH, except 0–0 S(3), which was observed with IRS‐SL. All lines were detected in both nod positions except for the 0–0 S(2) line.
