IRS spectra from the SH module (10−20 μm) corresponding to the spaxels encompassing the on-source and atomic peak positions in Fig. 1 (lower and upper panels, respectively). Both positions are dominated by strong atomic emission lines. No H2 emission is detected at the on-source spaxel. CO2 ice absorption bands are prominent in both spectra, indicating extended continuum emission to angular distances >5 ″ and a foreground absorbing layer.
