Spectral classification of an A-type supergiant (star 729). The MUSE spectrum (in black) is compared to four standard star spectra of spectral type A0 Ia, A0 Ib, A0 III, and A0 V. The continuous line shows the original spectra, and the dash-dotted lines show the spectra rotationally broadened by 200 km s−1. All standard star spectra are downgraded in resolution to match the MUSE data. We classify this star as early A-type star with luminosity class Ia-Ib.
