Spectral templates used on the MRS simulated observations (see Table 2 for details). Upper panel shows the brightest optical and near-IR emission lines in the range from Hβ to Paβ. The bottom panel is a zoom-in of the dashed line rectangle shown in the upper panel, and illustrates the fainter optical and near-IR emission lines in the range from Hα to Paβ. The spectra have a line width of 154 km s⁻¹ (FWHM) and are normalized to the peak of the [OIII]0.5007 μm emission line; the continuum is set to zero.
