Photometric properties of NGC 4330. Left panels: NGVS i-band image at low contrast (upper panel) to see the distribution of the absorbing dust within the disc, and at high contrast in logarithmic scale (lower panel) to see the boxy shape of the disc at its edges. The red and blue ellipses indicate the i-band mean surface brightness μ(i) = 23.5 and the effective surface brightness μ_e = 21.5 mag arcsec⁻², respectively. The green bullet and the red cross indicate the position of the photometric and kinematical centres, respectively. Right panels, from top to bottom: radial variation in the i-band surface brightness (μ), position angle (PA), ellipticity (ε), morphological inclination (i_ph), and the fourth degree cosine coefficient of the Fourier series (B₄) parameters. The red and blue vertical lines correspond to the ellipses drawn in the upper left panel and indicate the radius R_23.5(i)∼145.0 arcsec (∼11.6 kpc) and the effective radius R_e(i)∼66.5 arcsec (∼5.3 kpc), respectively.
