EW(Hα) map of the nearby spiral galaxy NGC 0309 (D = 75.8 Mpc) displayed in the range between 3 and 80 Å. The EW(Hα) map has been obtained from IFS data from the Calar Alto Legacy Integral Field Area (CALIFA) survey (Sánchez et al. 2012; García-Benito et al. 2015) through their processing with the pipeline PORTO3D (Papaderos et al. 2013; Gomes et al. 2016), as detailed in BP18. Contours delineate the stellar surface density, Σ_⋆, in M_⊙ kpc⁻² on a logarithmic scale from 8.2 to 9.3 in increments of 0.1 dex. The horizontal bar corresponds to a projected linear scale of 5 kpc. The EW(Hα) morphology of NGC 0309 is typical of massive local LTGs with an old SF-quenched bulge immersed within an extended star-forming disk (e.g., Catalán-Torrecilla et al. 2017; Belfiore et al. 2018; Breda 2019; Kalinova et al. 2021).
