Comparison of three different aperture spectra (blue, green, and red) with the TDOSE spectrum of ID_Guo = 9726 shown in Fig. 7 (thick gray) extracted based on a multi-component object model. The radii of the apertures are (blue), (green), and (red). Top panels: postage stamps of the HST F814W and the MUSE white light images with the aperture sizes marked by the colored circles. Bottom panels: zoom-in on the emission line free continuum blueward of the Hγ line. The largest aperture (red) recovers the most flux, but suffers from a lower S/N. On the other hand, the median-aperture extraction (green) provides the highest S/N, but suffers from a lower recovered flux. The spectrum extracted with TDOSE (thick gray) recovers the same flux as the large-aperture spectrum, but also has a S/N similar to the median-aperture extraction. See Fig. 9 for similar effects for a sample of 153 fainter [OII] emitters.
