MUSE spectrum of NGC 4593 extracted within a -radius aperture obtained in NFM-AO-N on 28 April 2019. The upper panel shows the full spectrum with the most prominent narrow and broad emission lines labeled. To enhance weaker emission features, the lower panel shows a close-up of the spectral continuum. The linear pseudo-continuum used for further analysis of the Ca II triplet + O Iλ8446 complex is indicated by a gray line. Regions affected by telluric absorption bands are indicated by gray shading.
