Spatially resolved estimate of the ionised gas electron density and dust attenuation in the circumnuclear region of NGC 424 obtained from the [SII]λλ6716,6731 doublet and Hα/Hβ ratio of MUSE data. Spaxels at S/N ≤ 5 are masked. Left panel: Red, cyan, and blue contours represent the 350, 325, and 300 km s⁻¹ contours of the broad component of the [O III] velocity dispersion map shown in Fig. 6. North is up, east to the left.
