SED fitting on Alba’s tidal features. The measured SEDs and fitted spectra of the left and right panels show the inputs and outputs of CIGALE for both J-PAS and SDSS. They correspond to the named polygons of Fig. 1 with the same color. Circles show fluxes from 56 narrow/medium-band J-PAS filters, while triangles represent SDSS’s five broad filters. Fitted CIGALE spectra are overlaid using gray (SDSS) and colored (J-PAS) lines. The residuals between the SED fitting results of both surveys and their respective observed fluxes are presented in Appendix. A (Fig. A.1). The dataset underlying this plot is publicly accessible through Zenodo (see Appendix E.4).
