Kinematical properties of the HII regions of IC 3476 with luminosity L(Hα) ≥ 10³⁶ erg s⁻¹ and S/N > 5, where the instrumental limit in the velocity dispersion is σ ≃ 13 km s⁻¹. Upper left: Hα luminosity vs. velocity dispersion. Upper right: equivalent diameter vs. velocity dispersion. Lower left: electron density vs. velocity dispersion. Lower right: kinematical age vs. equivalent diameter. The red filled symbols indicate HII regions located on the front structure and the green empty symbols indicate other HII regions within the stellar disc, respectively. All Hα luminosities are corrected for [NII] contamination and for Balmer decrement using the [NII]/Hα and Hα/Hβ ratios measured using the MUSE data within each individual region. Equivalent diameters and electron densities, defined as described in the text, are only plotted for HII regions where the PSF correction is less than 50%. The black solid line and the dotted lines show the mean relation and the envelope of points derived in the LMC by Ambrocio-Cruz et al. (2016).
