Illustration of extraction of multiple spectra while de-blending with TDOSE. Top panels (from top left to bottom right): postage stamps of the HST F814W image, the multi-component GALFIT model and residual, the MUSE white light image, and two narrowband images around [OII] of widths 1000 km s⁻¹ in rest-frame positioned at redshifts 0.52 and 1.39, corresponding to the redshifts of object ID_Guo = 9726 (ID_MUSE-Wide = 125017033) and ID_Guo = 9496 (ID_MUSE-Wide = 125068147), respectively. Bottom panels: TDOSE spectra extracted for object ID_Guo = 9726 (gray) and ID_Guo = 9496 (black) based on the multi-component GALFIT model (top central panel). First two panels: full spectra and the position of prominent emission lines at the redshift of the two objects. The gray shaded regions show the location of the flux and S/N zoom-ins shown in the bottom two panels. Due to the efficient de-blending by TDOSE, the continuum and emission line contamination in the spectra is low, and reliable flux estimates can be obtained based on these extractions. Figure 8 shows a comparison between aperture spectra and the model-based TDOSE spectrum of ID_Guo = 9726.
