Fig. 5
Zoom around the region containing the stellar absorption features and the coronal line [CaVIII] at 2.321 μm for three of the objects where coronal emission is detected. Spectra correspond to the brightest spaxel in [SiVI] (see Fig. 4). The pPXF fitting of the stellar absorptions is plotted in blue, and the residuals from the fitting are shown as a red dotted line.
