Caption: Figure 3.

SN 2024abup spectrum spanning optical (FLOYDS) to MIR (JWST) +41 days after the V-band maximum. The top panel covers 0.4 to 14 μm and subsequent panels zoom in on the optical spectrum, the third covers 1 to 2.6 μm, the fourth covers 2.5 to 5 μm, and the last one covers 5 to 14 μm. All the major lines identified using the SUMO model (see Section 5.1 and Figure 6) are marked with dashed vertical lines. The complete spectrum is available as the data behind the figure in the online Journal.
