Panel a: three-color optical image of NGC 1365 combining observations performed through three different filters (B, V, R) with the 1.5-m Danish telescope at the ESO La Silla Observatory in Chile. The red box indicates the region analyzed in this work, corresponding to the MUSE FOV (∼1′ × 1′). East is to the left. Credit: ESO/IDA/Danish 1.5 m/ R. Gendler, J-E. Ovaldsen, C. Thöne, and C. Feron. Panel b: continuum emission from MUSE having collapsed the data cube in the range ∼5100–6470 Å, excluding emission lines and the sky residuals. The crosses mark the extraction regions of the spectra shown in Fig. 2.
