Images of NGC 4330. Panel a: full resolution VESTIGE continuum-subtracted Hα narrow-band image of NGC 4330 in linear scale. Panel b: NGVS i-band image. Panels c,d: PUMA and GHASP FP Hα monochromatic images, respectively. Panel e: NGVS i-band image. The dashed black ellipse and the inner ellipse indicate the surface brightness, μ(i) = 23.5, and the effective surface brightness, μ_e(i) = 21.5 mag arcsec⁻², respectively, and the green bullet indicates the photometric centre (see Fig. 1). Panel f: NGVS i-band image with marks on the zones of interest labelled by letters (A to M) and two parallel dashed lines at r₀ ∼ 30 arcsec (∼2.4 kpc), which divide the galactic disc into three main regions: north-eastern, central, and south-western (see Sect. 4). The cyan, red, and blue contours in panels a to d show the VESTIGE surface brightness Σ(Hα) = 0.3, 1.0, and 12.5 × 10⁻¹⁷ erg s⁻¹ cm⁻² arcsec⁻², respectively. The red contours from panels e and f show the VESTIGE surface brightness Σ(Hα) = 10⁻¹⁷ erg s⁻¹ cm⁻² arcsec⁻². The blue contours in panel e indicate the surface brightness limit of PUMA, Σ(Hα)∼3.5 × 10⁻¹⁷ erg s⁻¹ cm⁻² arcsec⁻², while those in panel f show the surface brightness limit of GHASP, Σ(Hα)∼10⁻¹⁷ erg s⁻¹ cm⁻² arcsec⁻².
