Mid-infrared spectra in NGC 5728. The spectra for three apertures, corresponding to the nucleus (blue; region 4 in Fig. 5), star forming arc (red; region 1 in Fig. 5), and hotspot (green; region 2 in Fig. 5) are shown on a logarithmic flux scale. The spectra have been extracted from each of the 12 separate datacubes and overplotted. They show that no re-scaling between the cubes is needed. The most prominent lines with reliable identifications have been marked: 36 fine structure lines, 3 H I lines, and 8 H₂ lines.
