Illustration of extraction of galaxy (object ID_Guo = 9640, ID_MUSE-Wide = 102009072) and star (object ID_Guo = 9777) spectrum while de-blending with TDOSE. Top panels: postage stamps of the HST F814W image, the two-component GALFIT model, the MUSE white light image, and a narrowband image around the [OII] emission of the galaxy at z = 0.34 from the MUSE data cube. Bottom left panels: aperture spectra extracted for the two objects, indicated by the circles in the top left panel. The aperture sizes were set to of the galaxy ID_Guo = 9640, providing a good compromise between flux and S/N (see Fig. 9). The three panels show the full spectrum and zoom-ins on the Hβ and [OIII]λ4959,5007 Å emission lines region (gray box in the top panel). Bottom right panels: identical to the bottom left panels, except that now the spectra shown were extracted with TDOSE based on the two-component GALFIT model (top second panel).
