Panel a: stellar velocity map of NGC 1365, with respect to its systemic velocity, for which a value of 1630 km s−1 with respect to Earth has been considered. The map has been obtained from the fit of stellar continuum and absorption lines carried out on the Voronoi-binned data cube. Panel b: [O III] velocity map with respect to the systemic velocity. The velocities are the 1st-order moments of the total line profile resulting from the fit of the star-subtracted smoothed (with 1-spaxel σ gaussian kernel) data cube. The map has been re-smoothed with a Gaussian kernel having σ = 1 spaxel, for a better visual output, and a signal-to-noise cut of 3 has been applied (this holds for the other maps reported in panels c, d, and e of this figure, too). Panel c: [O III] velocity subtracted spaxel-by-spaxel by the stellar velocity. Panel d: [O III] W70 map, i.e difference between the 85th-percentile and 15th-percentile velocities of the fitted line profile. Panel e: Hα velocity map with respect to the systemic velocity. Panel f: Hα velocity map spaxel-by-spaxel subtracted by the stellar velocity.
