MUSE RGB image composition of the galaxy NGC 3456 where the O [III] emission is blue, Hα is green, and S II is red. The top panel in the right column shows the MUSE pointing from where the observation of the galaxy was taken, obtained from the ESO Archive Science Portal and based on a Digitized Sky Survey (DSS) colored image of the galaxy. The galaxy is located at z ≈ 0.0142 and hosted the SN Ic 2018ie, where its position is marked by the yellow star. The middle panel in the right column shows the Hα luminosity, with the markers indicating all H II regions identified by IFUANAL and used to obtain the other parameters from the datacube. The bottom panel reports the physical parameter map for the oxygen abundance of the segmented H II regions obtained from IFUANAL.
